What factors will affect the effectiveness of gas detectors
As one of the commonly used detection instruments in industrial production, gas detectors 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 frontdesk 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 content of oxygen in the atmosphere.
If the temperature fluctuation in the workspace is significant, the detection results of the gas detector may drift. In this case, the gas detector should be zeroed on site, which can greatly reduce the impact of temperature on the detection results of the gas detector. If the air humidity in the workspace increases and the 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 detection 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. For these leaked gases, we need to detect them in real-time. At this point, the Ousenjie VOC gas detector is essential.
Toxic and harmful gases such as alkanes, benzene, alcohol, gasoline, hydrogen gas, hydrogen sulfide, carbon monoxide, etc., once leaked, will mix with the surrounding air to form a mixture with explosive hazards, thus forming an explosive hazardous area. In explosive hazardous areas, once there is a fire source or heat source, and the concentration of combustible gas is within the explosion concentration range, it will cause fire and explosion accidents, causing huge losses to people's life 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 frequent occurrence of dangerous accidents.
