How heart rate sensor works

Most people cannot work with a coach or coach, but that does not mean that they cannot make the most of their professional time. A heart rate monitor goes a long way so you can get the most out of your running sessions.

Why this can help

Running, like many other exercises, puts a lot of stress on the runner system. If not monitored, this effort can end up causing damage. Usually what happens is that our body learns to change and adapt to the conditions it is subjected to, and running is no different. People make the mistake of disproportionately increasing the running time, making it difficult to control the body. Gadgets like these can help people see how well they perform and how much more they can increase.

What you do not know

A heart rate monitor lets you know what you are doing right and where you are doing it wrong. You don’t have to ask yourself if the last mile was a mistake or if you were really trying to push the limit. After discovering the basics of your heart rate, you can easily navigate your running session with the help of this cool little device. It is a fact that professional athletes use these monitors to measure their performance, but it is also true that anyone can buy a heart rate monitor and improve their exercise routine.

Choose your pace

Often, people are unable to decide the pace that suits them, or their path, because they misjudge their own strength or ability to run. When they are climbing, they may experience more fatigue and slow down, or even force their step to a point that their body cannot handle. A heart rate monitor helps because it lets you know the limit to which your heart is pushing. If they are going to slow down, the heartbeat indicates that they need to speed up and vice versa. There is no guessing game where you end up putting your own health at risk.

These devices are very easy to use and are especially useful for the elderly or people with health problems. A healthy lifestyle includes a good amount of exercise, but having said that, it is important to ensure that the person does not overdo it and end up trying too hard.

Things One Must Know About Air Conditioning!

In warm climates, every home has the facility of air conditioning nowadays. Earlier air conditioning was considered as luxury items at home. But now, due to these hotter summer days, it has become a necessity. Everyone nowadays is thinking to install an air conditioning system in their homes. But before you go for it, there are many things one must know. If you are wondering what things to know, don’t worry, we have made this post for you to know about those things only. The details break down below will let you know about a few things about air conditioning. But before we start the discussion, make sure to hire the best AIR CONDITIONING SUPPLIERS. If you do not hire the right suppliers, it will create a problem for you.



The air conditioner’s main purpose and function are to remove the heat from inside the home and throw it outside to keep the house cool. The air conditioner throw cool inside the home and throw the hot air outside the home. The energy used to make all this done is by a motor, which basically runs the compressor of the AC also.


If you want your air conditioner to run for long period, it is very important to maintain it on regular basis. A little maintenance can be done the consumers themselves, but on the other hand, a little maintenance requires professional service. What a consumer can do is, he can change the filters himself regularly to keep the air conditioner clean and blows appropriate cooling inside the room. You can even wash the filters when these catch a lot of dirt and debris. No doubt, you can change the filters by yourself; else the servicing should be done by the professionals only. It will be good to remove the debris and obstructions from the coils to maintain the cooling power of the AC. If the consumer is not finding this easy to be done, then don’t try to do it also. Just call the professionals and get the service done for better performance of the air conditioner.

Sometimes the air conditioner does not blow proper cooling, at that time may be it is the indication for the refrigerator reducing its airflow problems. These problems cannot be solved at home, so call a professional to get this done as soon as possible.


Humidity is the main problem, which is solved by the air conditioning. Usually what people think is, the air conditioner throws out the heat outside, but that is not the truth. What an air conditioner do it, it passes out the humidity from the house and throws cooling. The main job of it is to control the temperature. The only air conditioner cannot deal with both; cooling and humidity. That is why; compressor is made to let both the functions work properly.

If you want to know something else about the air conditioner, just ask from the AIR CONDITIONING SUPPLIERS. The suppliers will help you to know everything, which can help you to manage the regular issues of air conditioner.

Chemical Etching Process Used By Qualitetch for Manufacturing High Precision Parts

Qualitetch is a company that produces various types of high precision metal components for over 25 years by using a chemical etching process. Before knowing more about the products manufactured by Qualitetch you should know what the process of chemical etching is.

What is Chemical Etching?

Chemical etching is a process that is used to manufacture high precision metal components by using the process of subtractive etching. In this process, baths containing chemicals at regulated temperatures are used to remove selective material from the sheet of metal to produce high-quality metal components of desired shape and design. In this way, the chemical etching process can be defined as a process of manufacturing high accuracy parts of metal. It is also known as the process of electrochemical etching and photo etching etc.

The chemical etching process is time and cost-saving process of manufacturing the metal parts with a variety of burr-free flexible designs as compared to other processes of micro-manufacturing like EDM, stamping, laser cutting, water jetting and CNC, etc. It can be used for producing industrial grade as well as a prototype of the high precision metal parts. Qualitetch uses this process for manufacturing a number of high precision products like a variety of motherboards etc.

Working of the chemical etching process

The team of professionals of Qualitetch has to follow a number of steps before using the chemical etching process of the metal sheets. These steps include cleaning of the metal sheet followed by laminating, exposing, developing and etching it. After etching the sheet a stripping process is done before supplying the components to the customers after their rigorous inspection.

The metal sheet used for the chemical etching process is known as a substrate which is first of all laminated with a layer of light or photo-sensitive solution. Selective parts of the metal sheet are then exposed to UV light to develop a positive image of the product design on the sheet. The patterned substrate is then exposed to the chemical etching solution to get the final product by removing the unprotected parts of the metal substrate. In order to get the best results, all the steps are performed under extremely controlled conditions.

Why Qualitetch uses the Chemical Etching process?

Qualitetch uses the chemical etching process to produce high precision metal parts with multiple layers and complex designs. It is the best process for this purpose as the possibility of an error on etched features is +/- 10%. It is specially used for creating sharp edges, profiled or straight edges and round holes as desired in the design of a metal part.

The chemical etching process is an extremely cost-effective and time-saving process for large scale productions as well as for producing prototypes as compared to other modern as well as traditional manufacturing methods like EDM, CNC machining, pressing, stamping, laser cutting, and wire erosion, etc. Qualitetch uses this process for producing prototypes and industrial productions at a rapid rate as it is scalable and involves flexible tooling.

Importance of Etching Steel in Today’s Manufacturing Industry

The etching is a process traditionally used to cut into a metal surface to create an incised design by using a mordant or strong acid. Today different types of chemicals are used for etching different types of metals. Like engraving, etching is also used widely as one of the most important techniques for making prints of old master prints. Traditionally etching can be done on various metal surfaces including zinc, copper, and steel, etc. During steel etching, the area of the metal surface that is not to be etched is covered with an acid-resistant material like wax so that etching can be confined to its unprotected part.
Why steel etching is important?
The process of chemical etching is used on steel surfaces to manufacture components and parts for various industries in a very controlled and specific manner. Etching steel is considered as part of the subtractive manufacturing industry.
How steel etching work
The process of etching on steel surfaces includes the use of etching materials under a temperature controlled environment so that it can eat it away according to the design exposed to the etchant. The rest of the part of the steel surface will be covered by using a resistant to the etchant used for this purpose.
At the end of the process, you can get a design produced on the steel surface as if it has been engraved on it. In this way, etching can create all types of designs regardless of the level of their complication.
Benefits of steel etching
The demand for etching steel is increasing day-by-day in the manufacturing industry due to its various benefits like:
Easy to use: You need not make any special effort for using etching process on steel surfaces for printing design. Before applying a resistant to etchant on a steel surface you will have to clean it thoroughly so that the templates of the design can be printed easily on the surface. The chances of any error in the design of the template can be negligible because instead of hand-drawn designs they are CAD designs. You need not worry about any error in the final design even if it is very complicated, delicate and elaborate or etched on a very thin sheet of steel.
No harm to steel sheet: During the process of chemical etching of steel no stress or pressure is applied to the sheet. So, the integrity and the properties of the metal sheet used for this purpose remain unchanged until the process is complete. The properties and integrity of metal sheet can be at risk in other methods of creating designs like laser cutting, punching or stamping, etc. The design created by etching steel sheet very clear and precise.
Materials can be etched half: Sometimes various procedures are adapted to complete a design. In such cases, people usually need half etched designs so that other process can be followed to complete it. While etching the steel sheet with chemicals it can be possible to etch some parts of the design as per the requirement of the customer.
So, if you are searching for a service for etching steel surfaces then you can contact at https://www.qualitetch.com/ anytime.

Heart Rate Measurement Device

You have decided to start using a heart rate measurement device as part of your workout regimen and are wondering if there are any tips that can help you optimize its use. These devices have become rather common and they are not just a fad – they help people monitor not just how effective their workouts are, but also their overall health in the course of time. They come in many shapes and sizes and the most important tip is this: buy one that you will actually use.

It is easy to assume that since you want to monitor your heart it makes sense to buy a monitor that you will strap across your chest. What you may not realise is that these monitors come with such an array of problems that many people who buy them chose not to wear them after a few tries. They slip, they cause chafing, they are uncomfortable and they get in the way of a normal workout. There are devices that can monitor your heart rate perfectly without all these problems. They can be worn on your wrist, your ankle, your finger and on a visor or a baseball cap.

The other important thing is to check your heart rate in the morning, it is usually calmest when you wake up, so before you get into the swing of things you should check it – a normal heart rate is between 60 and 80 beats a minute. This way, you can compare whatever results you get during the day with your resting heart rate – you can, for example, see how much stress affects your heart rate – the higher it is the worse for you. Remember to measure your recovery rate too.

Try a heart rate monitor from Equivital – they have some of the most accurate in the market, and you can see some of them on     http://www.equivital.co.uk/.

What is Photochemistry?

Photochemistry is a branch of science that has to do with chemical reactions and the reactions which happen by the means of the absorption of light waves which are also known as the photons of a particular energy. Such reactions may only be caused by radiation which measures from 800 nanometers to 200 nanometers. Apart from that, the photons also have to possess enough energy in it too so that it would be able to raise the atoms from its initial ground state to that of the excited state. Atoms or a group of atoms can undergo a certain chemical reaction much faster when these atoms are in an excited state and a rapid chemical reaction would not be able to take place if the atoms are in a ground state. Just as soon as an atom moves from ground state to an excited state, that particular atoms are said to be promoted from a bonding molecular orbital which also known as BMO to that of antibonding molecular orbital ABMO. It is also important for you to keep in mind that whenever a ray of light falls onto a specific metal surface, the amount of light that is being reflected mostly depends on the type of metal surface. Besides that, the definition of photochemistry provided by Wikipedia is the branch of chemistry that focuses on the chemical effects that are caused by light. In general, the term ‘photochemistry’ is used to define a certain chemical reaction that is produced from the absorption of the visible light, ultraviolet rays, or the radiations of the infrared. Consequently, this means that there are a lot of outcomes produced from the chemical reactions that have the potential to be affected by the light. The branch of photochemistry becomes more and more important with rapid development in solar technology as the reactions that happen between solar light and chemicals are going to produce electrons or to be exactly transferring the photons that are absorbed from the light to electrons which in turns produced electricity. There is a wide range of the concepts of applications of photochemistry that are very useful. Such an example of the applications of photochemistry can be found in the recent discovery and development of laser technology which can be used in biomedical treatment such as photodynamic therapy and photo diagnostics. So to summarize it, photochemistry is a chemical reaction that will only occur by the absorption of UV, visible or infrared light. To pursue the reaction, one of the reactants in the chemical reactions has to be in a state of excited or activated. To make the chemicals to be reacted, a light source is needed and usually, the reactions are quite slow due to low kinetic energy. Keep in mind that the activation energy barrier is overcome by the absorption of light energy. Other perfect example for this process is the production of vitamin D from lanolin which is the wool grease of sheep under a UVB light.
