How to choose a combustible gas detector correctly?
Combustible gas detector is a combustible gas detector is an instrument that responds 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 detectors are one of the commonly used safety instruments for gas, petroleum, chemical, exercise, steel mills, etc. How should we choose a suitable gas detector?
01. First of all, it is necessary to clarify which one or several gases need to be detected
The gases that need to be detected are generally divided into two types: flammable gas and toxic gas. The corresponding ones are flammable gas detectors and toxic gas detectors. There are many gases such as natural gas and liquefied petroleum gas. After determining the gas we want to detect, we can proceed to the next step of purchase.
02. Different usage environments have different options
After determining the gas to be detected, we need to choose fixed or portable, diffusion or pump suction according to the environment in which the gas is produced and the requirements of the detection. Many industrial sites require real-time 24-hour online detection. At this time, it is recommended to use fixed combustible gas detectors. In some confined spaces or environments with relatively low gas hazard coefficients, diffusion and pump suction detectors can be considered according to their own needs.
03. Choose according to the measuring range to be tested
Different gas detectors are used for different gases, and the range required for the same gas is different due to different environments and requirements. The same brand of detectors with different ranges for the same gas has different prices. Only by choosing a high-quality instrument that meets your own measurement range requirements and is reasonably priced can we solve the purpose of our company's safe production.
04. About the choice of quantity
Understand the area of the site that needs to be detected: According to national regulations, the effective detection radius of flammable gas detectors is 7.5 meters, and the effective detection radius of toxic gas detectors is 1 meter. Calculate the number of gas detectors that need to be installed based on this detection radius.
