Does the gas detector need to be calibrated on a regular basis?
In order to use it accurately and safely, we need to calibrate the gas detector regularly. The core component of the gas detector is the sensor. The service life of the sensor is counting down from the first day it is produced. Even if you do not use the gas detector, it still requires you to calibrate it in three months, six months, or one year. Check or replace sensor. In addition, all gas detectors use relative measurement methods, so they require timely maintenance and calibration. Only by calibrating at any time according to the manufacturer's requirements can the expected accurate results be obtained. Places where this kind of calibration can be done include national departmental metrology institutes, and it can also be sent to the domestic after-sales service department of the manufacturer. The reports issued by them are different, but they can all make the instrument work normally.
In addition, in order to ensure the accuracy of the gas detector and extend its service life, we need to pay attention to the following issues when using the gas detector.
1. Portable gas detectors should be used rationally and the components should be checked for abnormalities at all times. If there are any abnormalities, they should be repaired or replaced with new ones in time to ensure that they can be used normally.
2. The gas detector is explosion-proof and explosion-proof equipment and shall not be used beyond the specified range.
Introduction to carbon monoxide gas detector performance requirements
1. The measurement range of the carbon monoxide gas detector should reach 0-2000umol/mol, and the maximum measurement value should not be less than 2000umol/mol.
2. The error of the indicated value of the carbon monoxide gas detector should be within the range of ±5umol/mol, and the relative error should be within the range of ±10%. Accurate readings can better express the concentration of the gas.
3. The response time of the carbon monoxide gas detector should meet the following standards: the response time of the diffusion carbon monoxide gas detector should be less than or equal to 60 seconds, and the response time of the inhalation carbon monoxide gas detector should be less than or equal to 30 seconds.
4. The drift degree of the carbon monoxide gas detector should be within the following range: zero point drift should be ±3umol/mol; range drift should be ±5%.
