Maintenance Precautions for Combustible Gas Detectors
Avoid continuous long-duration charging in daily use. The detector shall be powered off during charging. This not only shortens charging time but also extends the service life of the detector. If the detector is charged while powered on, its sensor may be affected by the charger, resulting in unexpected alarms or incorrect gas readings.
Second, avoid contact with water (this requirement also applies to models with a high protection rating).
Many operators use damp cloths to wipe the screen or outer casing of the combustible gas detector in daily operations, which constitutes improper maintenance. If moisture or water vapor seeps inside the detector, it may damage the circuitry and impair alarm accuracy. Likewise, combustible gas detectors must not come into contact with corrosive substances, as these can cause damage to the unit.
Third, perform regular charging during idle periods.
Combustible gas detectors in many facilities see infrequent use and are simply left idle. This practice offers no maintenance benefit and will shorten the service life of the device. When not in use, the detector should be charged once every 2 to 3 months to preserve normal battery life.
Fourth, prevent frequent impacts and drops.
The combustible gas detector must be kept in a secure location under normal conditions. For testing in special sites, select a proper position before starting measurement. Although the outer casing of the detector is built to withstand external force, repeated knocks, impacts or falls will degrade measurement accuracy and cause irreversible damage.
The above are key precautions for daily maintenance of high-quality combustible gas detectors.
In addition, avoid testing this device in environments with high concentrations of combustible gas. Power it up in an environment with normal gas levels, wait for initialization to complete before transporting it to the testing site for gas measurement. Proper daily maintenance is critical and directly determines the service life of the detector.
