What is the service life of a gas detector?
1. Regularly calibrate gas detectors. Generally, after one and a half years of use, the accuracy will decrease and must be recalibrated at the factory. Do not attempt to damage the sensor for a short period of time.
2. The longest service life of a gas detector is 5 years, which does not mean that all gas detectors can reach 5 years. This is only possible when the gas environment is relatively mild and daily protection is in place, and after the service life, a new detector must be replaced.
3. The sensors used for detecting the concentration of combustible gases in gas detectors are mostly catalytic combustion sensors, with a service life of 3-5 years in ideal environments. In addition, the lifespan of gas detectors (including fixed gas alarms and portable gas alarms) is closely related to the concentration they are exposed to.
4. The service life of electrochemical gas detectors is generally about 2 years. After 2 years, it is necessary to test the performance of the instrument to determine whether the detector needs to be replaced. In addition to necessary sensor aging, the detector also needs to be calibrated. Calibration of instruments requires the use of corresponding standard gases.
The service life of a gas detector is not necessarily determined, as it is closely related to the operating environment of the equipment. During the use period, it is necessary to punctually calibrate and check the protection of the gas alarm. Once problems arise, it is necessary to promptly contact skilled personnel or manufacturers. If the sensor fails, it is necessary to replace the sensor in a timely manner to avoid safety accidents.
How often is the gas detector calibrated
For instruments, calibration is necessary after prolonged use, and gas detectors are no exception. The calibration of gas detectors is actually similar to the annual audit of automobiles. Firstly, because the instruments have been used for a long time and for the sake of ensuring the quality of the instruments, it is necessary to find an instrument calibration agency to perform instrument calibration and correction once a year, and the measurement agency should issue a testing report. Secondly, because the country also has requirements, according to national regulations, it is difficult to obtain recognition without a testing report.
Therefore, in order to ensure the accuracy of gas detector readings, it is necessary to regularly recalibrate the gas detector. So how often does it take to recalibrate the gas detector?
In general, gas detectors are calibrated once a year, and strict testing instruments are calibrated every six months or three months. The more calibration times, the less likely the detector is to drift and the better the detection effect.
