Catalytic Combustion Detectors Can Offer You Reliable Gas Detection

Posted by SRI Instruments on November 30th, 2020

Closed spaces or we can say confined areas of chemical plants, refineries, and mines, can at times be filled with toxic and combustible gases. When such gases are present, needless to say the level of breathable oxygen goes down. When you need to work in such spaces, it is obvious that checking whether dangerous gases are present or not becomes crucial. This is something that can be achieved with the help of catalytic combustion detector in Torrance, CA. Apart from this, non-dispersive infrared (NDIR) sensor technology is also employed. In this article, we are going to discuss what these two methods offer and how they differ from each other. We have listed down some points for this purpose. Let’s take a look at them.

If we talk about catalytic combustion detection, this method has been in use for a long time now, almost 50 years. The main engineering in this method is developed around catalytic combustion (oxidation). It works quite simply. As soon as combustible gas mixtures arrive at their burning temperature, they begin to ignite. The process becomes faster when some chemicals are present, which is known for initiating the oxidizing process of a gas molecule at a lower temperature than usual. It has been found that certain metal oxides and their compounds posses amazing catalytic properties. You can better gas sensors stability by coating them with metal oxides. The best thing about catalytic detectors is that they are affordable, dependable, and work with most gases.

Now, let’s talk about NDIR. This technology is purely dependent on the absorption of a gas molecules of infrared energy with the help of bonds of dissimilar atoms. The distinct thing about non-dispersive IR sensors is that they determine gases within a fixed wavelength range linked with a particular gas. The reason why you may not have heard about this technology is because of its limitations. The biggest problem with NDIR is that it cannot work with those gases that do not have the ability to absorb infrared light. Examples include diatomic molecules such as hydrogen, oxygen, and nitrogen. Apart from this, there is another disadvantage with this technology and that is of warm up time and cost.

As you can clearly see, catalytic combustion detector is clearly a better way of checking gases. If interested, you can get this detector online from some top sellers that specialize in developing such key machines. You can also get cannabis lab testing equipment from them. So, contact one such seller and get the equipment you need for your projects.
