Use and maintenance method of combustible gas detector

There are many types and models of combustible gas detectors on the market today, and the basic circuit principles are the same, so the methods of using and maintaining combustible gas detectors are also similar. The following describes the use and maintenance methods of combustible gas detectors:
(1) The service life of detection components and compensation components is usually 3 to 5 years. Under the conditions of reasonable use and proper maintenance, the service life can be extended.
(2) For an alarm with a test button, the test button should be pressed once a week to check whether the alarm system is normal. The zero point and range of the alarm should be checked every 2 months.
(3) Always check the detector for accidental water ingress. The detector ventilation cover should be removed and cleaned during the instrument detection to prevent blockage.
(4) The detector is explosion-proof type explosion-proof equipment, and it should not be used beyond the specified range. The detector must not be used in sulfur-containing locations. The detector should be used under the condition that the concentration of combustible gas is lower than the lower explosion limit, otherwise, it may burn out the components.
(5) The thermal xian type semiconductor detector shall not be used under the condition of lack of oxygen. Do not use a large amount of flammable gas directly at the probe.
