As one of the most commonly used detection instruments in industrial production, the gas detector can detect the concentration of toxic and hazardous substances in production work and make an alarm when it reaches a predetermined alarm value to ensure the personal safety of frontline workers. So, what factors will effect when the gas detector is used?
When using the gas detector we must pay attention to the environment, there are many environmental factors can affect the detection results, such as humidity and temperature changes.
Changes in temperature affect the oxygen concentration in the atmosphere.If the temperature fluctuation in the operating space is large, the results may drift. In this case, the gas detector should be on-site zero correction, so as to minimize the impact of temperature on the detection results.
If the humidity of the air in the operating space increases and there is more water vapor in the air, it may cause the deviation of oxygen. This effect will not be noticed immediately, but it will slowly affect the oxygen reading over several hours, which lead to inaccurate test results.So we should pay attention to the temperature and humidity in the air when we use the gas detector in the air, and also calibrate the detector timely.
