How to clean and maintain the gas detector
1. Check the gas flow rate, usually 30/h, if the flow rate is too large or too small, it will have a great impact on the results of the analyzer
2. Replace the filter paper: stop the air pump and drain the filter tank
3. Check whether there is air leakage in the air system. Whether the sobbing pump diaphragm is damaged, whether the sealing ring of the sampling probe is broken, whether the four-way valve and condensing steam are damaged, etc.
4. Clean the sampling probe and unblock the sampling hole pipeline
5. Check whether the condenser works normally, usually the temperature is adjusted within 3 degrees Celsius
6. Check the measuring chamber to see if it is dirty and clean it in time.
Gas detector is a kind of instrumentation tool for gas leakage concentration detection, including: portable gas detector, hand-held gas detector, fixed gas detector, online gas detector, etc. The gas sensor is mainly used to detect the type of gas existing in the environment. The gas sensor is a sensor used to detect the composition and content of the gas.
It is generally believed that the definition of a gas sensor is based on the classification of the detection target, that is to say, any sensor used to detect the gas composition and concentration is called a gas sensor, no matter whether it uses a physical method or a chemical method. For example, sensors that detect gas flow are not considered gas sensors, but thermal conductivity gas analyzers are important gas sensors, although they sometimes use roughly the same detection principle.
