What are the factors affecting the service life 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. When the preset alarm value is reached, an alarm will be issued to ensure the personal safety of front desk personnel. So what factors will affect the service life of gas detectors? Below, the editor will share with you for better use of gas detectors in the future.
Factors affecting the service life of gas detectors:
1. Changes in temperature can affect the actual amount of oxygen in the atmosphere. If the temperature fluctuation in the workspace is large, the detection results of the gas detector may drift. In this case, the gas detector should be calibrated to zero on site to minimize the impact of temperature on the detection results of the gas detector.
2. As the humidity in the workspace increases, water vapor in the air can drive away oxygen, leading to a possible decrease in oxygen readings. This effect will not be immediately detected, but it will gradually affect the degree of oxygen and test results after a few hours. Therefore, when checking the air, attention should be paid to the temperature and humidity of the working air, and the detection instruments should be adjusted.
3. Currently, many gas detectors can replace their detection sensors, but this does not mean that one detector can use different detector probes at any time. Whenever the probe is replaced, not only does it require a certain amount of sensor activation time, but it also requires recalibration of the instrument.
4. Gas detectors have a fixed detection range for various toxic and harmful gas detectors. Only when the measurement is completed within its measuring range can the instrument accurately measure. If the measurement range is exceeded for a long time, it may cause permanent damage to the sensor.
Here, I would like to share the relevant content. Gas detectors are widely used for on-site detection in petrochemical, coal, metallurgical, chemical, municipal gas, environmental monitoring and other places. Can meet the measurement requirements of special occasions; Gas concentration or leakage detection can be performed on tunnels, pipelines, tanks, enclosed spaces, etc.
