Application areas and daily considerations for gas detectors
In order to ensure the high efficiency of gas detectors in various industries, users should pay attention to daily applications:
1. Regular calibration. It is generally recommended to calibrate the instrument for 6 months or 12 months. Use the standard gas to calibrate the meter. Follow the instructions of the instrument. Do not arbitrarily correct the calibration if there is no accurate target gas.
2, the gas detector sensor drift problem, this is an inherent feature, no matter how sophisticated it is, the sensor will have a small amount of zero drift every month, so zero calibration is required.
3. Gas detector sensors have different warm-up times due to different principles. Therefore, in order to ensure the best performance, it is necessary to start preheating in advance.
4, the gas detector is mainly to detect the gas concentration, so the sensor components, must not enter the water.
Specific application areas of gas detectors
1. Leak detection: On-site flammable or toxic gas and vapor leak detection alarms on equipment pipelines, equipment pipeline operation leak detection.
2, life detection: When a major earthquake and various disasters occur, mainly after people are buried in the soil, use a detector to detect where the human life is buried.
3. Emergency detection: When abnormal conditions occur at the production site or when handling accidents, flammable or toxic gases and vapours should be tested for safety and hygiene.
4. Inspection and inspection: After the equipment is replaced, the residual flammable or toxic gases and vapors are detected, especially before the fire is detected.
5. Tour inspection: When testing safety and hygiene, it is necessary to detect flammable and toxic gases or liquid vapors.
6. Entry test: When the worker enters the flammable and toxic substance isolation operation room and enters the ditch, cable trench or equipment in the dangerous place, it is necessary to detect flammable and toxic gas or liquid vapor.
