How to correctly choose a combustible gas detector?
Combustible gas detector is an instrument that reacts to the concentration of a single or multiple combustible gases. There are two types of combustible gas detectors: catalytic type and infrared optical type. Gas detector is one of the commonly used safety instruments in gas, petroleum, chemical, exercise, steel plants, etc. So how should we choose a suitable gas detector?
Firstly, 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 gases and toxic gases, corresponding to combustible gas detectors and toxic gas detectors. Combustible gases include methane, ethane, propane, butane, ethylene, acetylene, carbon monoxide, natural gas, liquefied petroleum gas, and many other gases. After determining the gas we want to detect, we can proceed to the next step of selection.
02. Different usage environments have different choices
After determining the gas to be detected, we need to choose between fixed or portable, diffusion or pump suction based on the environment in which the gas is generated and the requirements of the detection. Many industrial sites require real-time 24-hour online detection, and it is recommended to use fixed combustible gas detectors. In some enclosed spaces or environments with relatively low gas hazard factors, diffusion and pump suction detectors can be considered according to their own needs.
03. Choose according to the required testing range
Different gases require different gas detectors, and the required range for the same gas varies due to different environments and requirements. The same brand of detector for the same gas with different ranges also has different prices. Only by choosing high-quality instruments that meet our range requirements and are reasonably priced can we achieve the goal of safe production for our enterprise.
04. Regarding the selection of quantity
Understand the area of the location that needs to be tested: According to national regulations, the effective detection radius of combustible gas detectors is 7.5 meters, and the effective detection radius of toxic gas detectors is 1 meter. Based on this detection radius, calculate the number of gas detectors required for installation.
