In order to ensure the high efficiency of gas detectors in various industries, users should pay attention to:
1. Regular calibration. Generally, it is recommended to calibrate the instrument in 6 months or 12 months. Use standard gas to calibrate the instrument and follow the instrument operation instructions. Do not calibrate at will when there is no accurate target gas.
2. The drift problem of the gas detector sensor is an inherent characteristic. No matter how precise a meter is, the sensor will have a small amount of zero drift every month, so zero calibration is required.
3. The sensor of the gas detector has different preheating time due to different principles. Therefore, in order to ensure the best performance, it is necessary to start the preheating in advance.
4. The gas detector mainly detects the gas concentration, so the sensor parts must not enter the water.
Specific application areas of gas detectors：
1. Leak detection: flammable or toxic gas and vapor leakage detection and alarm on the equipment pipeline site, leakage detection of equipment pipeline operation.
2. Life detection: In the event of major earthquakes and various disasters, it is mainly after people are buried in the soil that detectors are used to detect where people's lives are buried.
3. Emergency detection: When an abnormal situation occurs at the production site or an accident is handled, the flammable or toxic gases and vapors should be tested for safety and hygiene.
4. Inspection and maintenance: After the equipment is repaired and replaced, it is more important to detect residual combustible or toxic gases and vapors, especially before fire.
5. Itinerant inspection: During safety and health inspections, combustible and toxic gases or liquid vapors should be detected.
6. Entry detection: When the staff enters the isolation operation room of combustible and toxic substances, and enters the sewers, cable trenches or equipment in dangerous places to operate, they must detect combustible and toxic gases or liquid vapors.
