As one of the most commonly used gas detection instruments, the gas detector can be used to detect the concentration of toxic and hazardous gases in work place. The gas detector can be used to detect the type of gas exsit in the environment, and use the corresponding safety protection equipment according to the detection result. So, what factors will affect the accuracy of gas detectors?
When using a gas detector, you must pay attention to the ambient environment. There are many factors that can affect the detection result, such as humidity and temperature. Changes in temperature will affect the detect result of oxygen actually present in the atmosphere. If the temperature in the working space fluctuates greatly, the results detected by the oxygen analyzer may drift. In this case, the gas detector should be zero-calibrated on site, so as to minimize the influence of temperature on the detection result of the oxygen gas detector.
If the humidity of the air in the working space increases, the water vapor in the air will drive the oxygen, causing the oxygen reading to cause a fall. This effect will not be immediately discovered, but after a few hours, it will slowly affect the degree of oxygen and affect the test results. Therefore, we should pay attention to the temperature and humidity of the air in the working air when testing the air, and even adjust the O2 detector.
