What factors will affect the use of gas detectors
As one of the most commonly used detection instruments in industrial production, gas detectors can detect the concentration of toxic and harmful substances in production work, and issue an alarm when the predetermined alarm value is reached, ensuring the personal safety of frontline workers. So, what factors will affect the use of gas detectors?
When using a gas detector, it is important to pay attention to the operating environment, as there are many environmental factors
Elements can affect the detection results of gas detectors, such as changes in humidity and temperature.
The change in temperature can affect the actual amount of oxygen present in the atmosphere. If the temperature fluctuation in the workspace is significant, the results detected by the gas detector may drift. In this case, the gas detector should be calibrated on-site to minimize the impact of temperature on the detection results.
If the air humidity in the working space increases and the water vapor content in the air is high, it may cause deviation in the oxygen reading. This effect will not be immediately detected, but after several hours, it will gradually affect the oxygen reading, ultimately leading to inaccurate detection results. So when we inspect the air, we should pay attention to the temperature and humidity in the working air, and then adjust the detector.
How to choose a suitable gas detector
The types of gases encountered by each production department are different. When choosing a gas detector, it is important to consider all possible scenarios. If methane and other less toxic alkanes are predominant, choosing an LEL detector is undoubtedly the most appropriate option. This is not only because the LEL detector has a simple principle and wide application, but also has the characteristics of convenient maintenance and calibration. If there are toxic gases such as carbon monoxide and hydrogen sulfide, priority should be given to selecting a specific gas detector to ensure the safety of workers. If there are more organic toxic and harmful gases, considering their lower concentrations that may cause personnel poisoning, such as aromatic hydrocarbons, halogenated hydrocarbons, ammonia (amines), ethers, alcohols, lipids, etc., it is absolutely not advisable to use LEL detectors to cope, as this may lead to personal injury or death.
If the types of gases cover the above categories, choosing a composite gas detector may achieve twice the result with half the effort. The types of gas detectors chosen vary depending on the industrial environment. The instruments are mainly divided into three categories: fixed gas d
