1. The actual amount of oxygen in the atmosphere is impacted by temperature changes. The gas detector's detection results may err if the working environment's temperature varies significantly. To reduce the impact of temperature on the gas detector's results in this situation, the gas detector should be calibrated to zero in the field.
2. The oxygen value may decrease as the air in the workspace becomes more humid because the water vapor in the air displaces the oxygen. This effect takes a few hours to become apparent but gradually lowers oxygen levels and alters test findings. The testing device should be adjusted and special attention should be paid to the temperature and humidity of the working air when checking the air.
3. Many gas detectors today have the ability to swap out the detection sensor, but this does not indicate that the detector can always utilize a different detector probe. Every time a probe is changed, the instrument must be recalibrated in addition to requiring a certain length of sensor activation time.
4. For different dangerous and harmful gas detectors, the gas detector has a fixed detection range. Only measurements that are completed within the measurement range of the instrument are correct. If the measurement range is exceeded for an extended period of time, the sensor may suffer permanent damage.
Share relevant content here. Gas detectors are widely used in on-site detection in petrochemical, coal, metallurgy, chemical, municipal gas, environmental monitoring and other places. It can meet the measurement requirements of special occasions; it can perform gas concentration detection or leak detection on tunnels, pipelines, tanks, closed spaces, etc.
