gas detectorAs a safety instrument, it is widely used in metallurgy, petroleum, chemical, municipal and other industries. When there is a danger of gas leakage in the environment, the alarm can be used to remind the staff to take safety measures to prevent explosions, fires, and poisoning accidents, so as to ensure safe production.gas detectorThe verification problem is a common problem, and the following editor will briefly talk about how often the gas detector is calibrated.
In general, whether it is combustiblegas detectorOr poisonousgas detectorAs time goes by, the sensitivity of the detector will gradually decrease, and the error will begin to increase, which needs to be checked regularly. According to the Metrology Law, gas detector is a measuring instrument subject to national compulsory verification, and the user unit needs to apply for verification, and the calibration period generally does not exceed one year.
In the actual use of gas detector, how often to check is mainly determined according to the actual situation, generally refer to the following situation:
1. Basisgas detectorThe verification cycle can be 3 months, 6 months, and 12 months. Generally no more than 1 year.
2. The measuring instruments for compulsory verification must be determined by the statutory or authorized measurement and verification institutions at regular and fixed points.
3. Measuring instruments (gas detectors) that are not compulsory can be regularly verified by the user in accordance with the law. If the unit cannot verify, the measurement and verification agency with the right to carry out the measurement and value transmission shall carry out the verification. The measurement verification work shall be carried out in accordance with the principles of economic reasonableness and local proximity.
4. The unit must conduct self-verification and calibration by the personnel who have obtained the measurement verification certificate.
