What do I need to be aware of when using a gas detector?
1. read the instruction manual carefully, operate according to the steps, do not modify the internal parameters. 2.
2. When installing, debugging, setting and other operations of the gas detector, it must be debugged by professional personnel, non-professionals are prohibited to operate. 3.
3. It is forbidden to shock the sensor with gas higher than the measuring range, and it is forbidden to expose the instrument to high concentration of corrosive gases (in special cases, pre-treatment is required).
4, in the process of gas detector operation, it is strictly prohibited to open the cover with electricity on the scene and replace the sensor with electricity.
5. when using the gas detector should not be thrown away or shaken vigorously to avoid internal failure of the instrument. 6.
6. Do not allow the replacement of components or structures that affect the explosion-proof performance, so as not to affect the explosion-proof performance.
7. Charging must be carried out in a safe place and use the charger provided with the instrument. It is strictly prohibited to disassemble, charge or replace the battery in dangerous places.
8. The calibration check of the gas detector should be carried out regularly, and the sensor which exceeds the expiration date and the faulty sensor should be replaced in time.
9. Fixed gas detectors need to be installed in a suitable location according to the detected gases.
10. Pay attention to the concentration measurement range of the instrument: all types of gas detectors have their detection range, and different models have different range values. Only by completing the measurement within its measuring range can the instrument be guaranteed to perform accurately. If measurements are made outside the measuring range for a long period of time, permanent damage may be caused to the sensor.
11. Pay attention to frequent calibration and testing: Gas detectors are measured using a relative comparison method. The instrument is calibrated with a zero gas and a standard concentration of gas, a standard curve is obtained and stored in the instrument, and the accurate gas concentration value is calculated. Therefore, zeroing the instrument at any time and calibrating the instrument regularly are essential to ensure the accuracy of the instrument measurement.
12. Pay attention to the detection of interference between different sensors: each sensor corresponds to a specific detection gas, but any kind of gas detector can not be an absolute special effect.
