First, Timely calibration and testing
No matter what instrument, it should be checked before use to make sure its accuracy,without timely correction and testing, the accuracy of the instrument may be deviated. In this case, if fire fighters enter the toxic gas leakage site, it may cause serious casualties.Therefore, before the use of gas detector, timely calibration and detection is very necessary.
Second, Pay attention to the measurement range
Gas sensor has a fixed detection range.Only when the measurement is completed within its measurement range, the detector can be ensured to carry out the measurement accurately.The sensor may be damaged if beyond the measurement range for a long time.For example, toxic gas detector, working in a high concentration of toxic gas environment for a long time, may cause damage to the sensor.Therefore, if the fixed detector sends out over-limit signal, the instrument should be turned off immediately.
Third, pay attention to the use environment
Pay attention to prevent electromagnetic interference during usage.In addition, the aimbient temperature, humidity, pressure, wind speed, wind direction, whether there is dust, corrosive, whether there is other gas interference will also affect the gas detector effect.
Four, pay attention to the maintenance of the detector
Do not place or hang items on the portable gas detector. The installed fixed gas detector cannot be moved frenquently. Try to choose products with replaceable sensor to facilitate maintenance and replacement later.
