Gas detector is one of the most commonly used detection instruments in industrial production. He can detect the concentration of toxic and hazardous substances in the work. The gas detector can detect the kind of gas in the environment. According to the test results, the corresponding Safety equipment.
When using the gas detector must pay attention to the use of the environment, there are many factors that can affect the gas detector test results, such as humidity and temperature changes.
Changes in temperature can affect the amount of oxygen actually present in the atmosphere. If the temperature fluctuation in the working space is large, the result of the gas detector may drift. If this happens, we should perform zero calibration on the gas detector so that the temperature can be minimized. The effect of the results.
If the air humidity in the workspace increases, the water vapor in the air will drive away the oxygen, causing the oxygen reading to cause a drop. This effect will not be immediately discovered, but after several hours it will slowly affect the oxygen level, affecting the test results
So we should pay attention to the air temperature and humidity in the air when testing the air in order to adjust the detector.
