How to choose the right detection of toxic and hazardous gas detector
1) Confirm the type of gas to be detected and the concentration range:
Every production department encounters different types of gases. When choosing a gas detector it is important to consider all possible scenarios. If methane and other less toxic alkanes are predominant, the choice of LEL detector is undoubtedly the most appropriate. This is not only because the LEL detector is simple and widely used, but also because it is easy to maintain and calibrate. If there are toxic gases such as carbon monoxide, hydrogen sulphide, etc., it is important to prioritise a specific gas detector in order to ensure the safety of workers. If more organic toxic and hazardous gases are present, taking into account their lower concentrations that may cause personnel poisoning, such as aromatic hydrocarbons, halogenated hydrocarbons, ammonia (amines), ethers, alcohols, lipids, etc., the photoionisation detector introduced in the previous chapter should be chosen instead of using a LEL detector to cope with them, which may lead to injuries or deaths.
If the gas type covers the above categories how to choose the right toxic and hazardous gas detector
For all kinds of different production occasions and detection requirements, choosing the right gas detector is every person engaged in safety and detection work must pay great attention to. Here we will do a presentation on some specifics for your reference.
If you use this type of instrument as an alarm in open situations, such as an open workshop, you can use a portable diffusion gas detector because it can continuously, real-time and accurately display the concentration of toxic and hazardous gases at the scene. Some of these newer instruments are also fitted with vibration alarm attachments - to avoid inaudible audible alarms in noisy environments - and computer chips to record peaks, STEL (15-minute Short Term Exposure Levels) and TWA (8-hour Statistical Weighted Average). -Provide specific guidance for worker health and safety.
