Value range of the four in one gas detector
What are the factors that affect 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, and emit an alarm when the preset alarm value is reached, thereby ensuring the personal safety of front-line personnel. So what factors will affect the service life of gas detectors? Next, the editor will share with you for better use of gas detectors in the future.
1. Changes in temperature can affect the actual amount of oxygen in the atmosphere. If the temperature in the workspace fluctuates significantly, 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.
As the humidity in the workspace increases, water vapor in the air will 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 detection results after a few hours. Therefore, when checking the air, attention should be paid to the temperature and humidity of the air in the working air, and the detection instrument should be adjusted.
Currently, many gas detectors can replace their detection sensors, but this does not mean that a single detector can use different detector probes at any time. Whenever a 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 measurement 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, let's share some 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 detection or leakage detection can be carried out on tunnels, pipelines, tanks, enclosed spaces, etc.
