The combustible gas detector is an instrument that responds to the concentration of single or multiple combustible gases. There are two types of combustible gas detectors: catalytic type and infrared optical type. The gas detector is one of the commonly used safety instruments in gas, petroleum, chemical, exercise, steel mills, etc. So how should we choose a suitable gas detector?
01. First of all, it is necessary to clarify which gas or gases need to be detected
The gases that need to be detected are generally divided into two types: combustible gas and toxic gas, corresponding to the combustible gas detector and the toxic gas detector. The combustible gas also includes: methane, ethane, propane, butane, ethylene, acetylene, carbon monoxide, Natural gas, liquefied petroleum gas and many other gases, after confirming the gas we want to detect, then proceed to the next step of purchase.
02. Different use environments have different choices
After determining the gas to be detected, we need to choose fixed or portable, diffusion or pumping according to the environment where the gas is generated and the requirements of the detection. Many industrial sites require real-time 24-hour online detection. At this time, it is recommended to use a fixed flammable gas detector. In some confined spaces or environments with relatively low gas risk factors, diffusion-type and pump-suction detectors can be considered according to their own needs.
03. Choose according to the measuring range that needs to be detected
Different gas detectors are used for different gases. The same gas has different ranges due to different environments and requirements. The same brand of detectors with different ranges of the same gas have different prices. Only by choosing a high-quality instrument that meets your own range requirements and the price is suitable can we solve the purpose of safe production in our enterprise.
04. The choice of quantity
Know the area of the site that needs to be detected: According to national regulations, the effective detection radius of the combustible gas detector is 7.5 meters, and the effective detection radius of the toxic gas detector is 1 meter. According to this detection radius, the number of gas detectors required to be installed is calculated.
