Principles and precautions for use of toxic and harmful gas detectors
Recently, gas detectors, an essential equipment in daily life, have become increasingly harmful to the environment with the development of the economy. If we want to live a better life, we need to use gas detectors to ensure our personal safety. However. What technologies are used for toxic and harmful gas detectors?
Firstly, it should be noted that a toxic gas detector is an instrument tool for detecting the concentration of toxic gas leaks, mainly referring to portable/handheld gas detectors. Mainly using toxic gas sensors to detect the types of gases present in the environment. Unlike combustible gas detectors, toxic gas detectors are not universal. Toxic gas detectors are a type of gas detector with strong specificity, and are selected based on the specific toxic gas being measured. For example, carbon monoxide detector and CL2 gas detector, although both are called toxic gas detectors, are completely different toxic gas detectors because they measure different gases. If a carbon monoxide detector is used to detect CL2 gas in the presence of HCL gas, the carbon monoxide detector will not respond.
That is to say, the carbon monoxide detector cannot detect CL2 gas, so before selecting a toxic gas detector, it is necessary to clarify which specific toxic gas is being measured. The toxic gas detector can be selected as either pump suction or diffusion type based on its toxicity level. If the toxicity of toxic gases is high and there is danger for personnel entering, a pump suction toxic gas detector must be selected. If the toxicity of toxic gases is not very high and may exist in trace amounts, but long-term inhalation can also cause danger, a diffusion toxic gas detector can be selected, such as in places where carbon monoxide is present.
