Introduction to several issues to be noted in the use of gas detectors
As one of the commonly used detection instruments in industrial production, VOC gas detector can detect the concentration of toxic and harmful substances in production, and issue an alarm when the preset alarm value is reached, thereby ensuring the personal safety of front desk personnel. So, what factors will affect the use of gas detectors?
When using a gas detector, there are many environmental factors that can affect the detection results of the gas detector, such as changes in humidity and temperature, which will affect the actual oxygen content in the atmosphere.
If the temperature fluctuations in the workspace are significant, the detection results of the gas detector may drift. In this case, the gas detector should be zeroed on site to greatly reduce the impact of temperature on the detection results of the gas detector. If the air humidity in the workspace increases and the amount of water vapor in the air increases, the oxygen reading may deviate and cannot be detected immediately. However, after a few hours, the oxygen reading will be slowly affected, resulting in inaccurate test results. Therefore, when checking the air, pay attention to the temperature and humidity in the working air, and then adjust the detector.
In the production, processing, and transportation processes of industries such as petroleum, chemical, and coal, various flammable and explosive gases or liquids may leak. We need to detect these leaked gases in real time. At this point, the Ousenjie VOC gas detector is essential.
Toxic and harmful gases such as alkanes, benzene, alcohol, gasoline, hydrogen, hydrogen sulfide, carbon monoxide, etc., once leaked, will mix with the surrounding air to form explosive mixtures, thus creating explosive hazardous areas. In explosive hazardous areas, once there is a source of fire or heat, and the concentration of combustible gases is within the explosive concentration range, it will cause fire and explosion accidents, causing huge losses to people's lives and property safety. Therefore, in order to ensure production safety, it is necessary to understand the characteristics of these toxic and harmful gases and use modern instruments for alarm detection to prevent the frequent occurrence of dangerous accidents.
