How many years is the typical lifespan of a toxic gas alarm?
Thread Content
Dear teachers, the domestic toxic gas detectors installed in the factory at the beginning of 2020; production began officially after the installation of these devices was completed in January 2021. During the mandatory inspection in October 2020, everything was normal. This year, during the mandatory inspection, it was found that there were over 100 instances where no alarm was triggered; even when the material was brought close to the sensor, no alarm sounded, and the measurement values remained at 0. Since its installation, it has been in use for no more than 15 months. Question: How many years is the lifespan of a toxic gas alarm? The on-site environment is excellent, with very little unpleasant odor.
You need to ask your supplier how many years this has a lifespan. . . . . But it seems to be a mandatory inspection once a year
The sensors of these combustible or toxic gas detectors generally need to be replaced once a year; their lifespan is quite short. Especially those used for detecting toxic gases operate on electrochemical principles, and the electrolyte in the electrolytic cell gradually decreases over time in an irreversible manner. Just like in electric vehicle batteries, over time it is necessary to top up the electrolyte, but this sensor cannot be recharged, and it eventually becomes unusable after some time. The sensor needs to be replaced
If the environment is good and the leakage rate is low, it shouldn’t stop working after 15 months; it is preliminarily inferred that a quality issue is likely.
Different types are adapted to different environments; when selecting, the testing environment medium should be taken into account.
Most manufacturers state that the lifespan of the probes in toxic gas detectors is generally 1–2 years; in environments that are favorable and where there is no leakage, the probes can last longer. If it is used in a place where there are constant leaks, the probe will become ineffective within a few months. To maintain toxic gas detectors properly, the costs are high, and the sensors need to be replaced regularly. Domestic Te’an and GreenTong are quite good.
Electrochemical devices do not have a long service life; under good operating conditions, they can generally work for two years without issues, but honestly, your device’s lifespan is indeed a bit short. . . It is likely closely related to quality; it is recommended to contact the manufacturer

General toxicity: 2 years, flammability: 3 years
It must be a quality issue; generally, if there is little gas leakage at the site, the device can function properly for several years. There is usually zero drift, and regular calibration is required; widespread damage does not occur.
