How often should carbon monoxide alarm gas leak detectors be calibrated ?

Carbon monoxide detectors are gas-sensitive components, most of which use electrochemical principles, and their sensitivity decreases over time. Therefore, we must check it regularly. So, how often do carbon monoxide alarm gas leak detectors check?

carbon monoxide alarm gas leak detectors

Under normal circumstances, the carbon monoxide alarm gas leak detector is checked once a year, according to actual needs, of course, the shorter the better.

1. The normal calibration time of the carbon monoxide alarm gas leak detector is no more than one year, and the period from the delivery of the product to the regular maintenance is one year. It is mainly based on the use time of the gas monitoring probe. The calibration is to avoid the decrease of the sensitivity of the monitoring probe. If the gas detector fails to monitor the gas concentration in time when the gas concentration increases, the sensitivity of the gas detector decreases or the instrument calibration occurs. question.

2. According to the place of use, frequency of use and the degree of influence on the production process of the carbon monoxide alarm gas leak detector, the verification period is determined, and the verification period can be 3 months, 6 months or 12 months.

3. The new sensor should be exposed to various environments more, even if it is not suitable for the environment. After using it for at most ten days, the daily sensor detection should be carried out in the atmospheric environment.

4. When the carbon monoxide alarm gas leak detector has operational changes and environmental changes, it should be re-checked.

The above is an introduction to how long it takes for a carbon monoxide alarm gas leak detector. Carbon monoxide detectors need to be tested at least once a year in order to detect carbon monoxide gas leaks quickly, accurately and stably.
