The progress of portable gas detector makes the leakage link can be detected in the early stage, and reasonably and effectively prevents the occurrence of some disasters, which is an important part of the safety accident prevention technology system.

Avoid multiple impacts and falls

The portable gas detector must be placed at a safe and specific location in peacetime. When testing in some special places, the specific location should also be selected before testing. Even if the external casing of the detector has the function of resisting external forces, if it is hit repeatedly or dropped from high altitude, the accuracy of the detector will be reduced and irreversible damage will be caused.

Do not overcharge for a long time
In normal times, try to reduce one-time long and fast charging, and keep the gas detector in the off state when charging, which can not only charge time, but also prolong the life of the detector. Since the gas detector is charged when it is turned on, the sensor of the instrument may be interfered by the charger, resulting in sudden alarm or wrong detection of gas.
 
Pay attention to regular charging when idle
In many areas, the frequency of selecting portable gas detectors is relatively low. In ordinary times, the instrument is directly left idle, which will not only have a maintenance effect on it, but also reduce its service life; When the gas detector is idle, it should be charged once within 2 to 3 months to protect the normal life of the battery.
 
Avoid contact with water
At ordinary times, many operators will choose wet cloth to wipe the display screen or external casing of the portable gas detector. This is a violation of maintenance, because if moisture or moisture enters the detector, the circuit of the detector will be damaged and the alarm accuracy will be disturbed; Similarly, the combustible gas detector cannot contact with corrosive substances, which will also cause corresponding damage to the detector.
