Detailed explanation of carbon monoxide gas detector needs
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 indication 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 indicate 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 ranges: the zero point drift should be ±3umol/mol; the range drift should be ±5%.
How to calibrate the gas detector?
A gas detector is an instrumentation tool for gas leakage concentration detection, including portable gas detectors, fixed gas detectors, etc. It mainly uses gas sensors to detect the types of gases that exist in the environment. Gas sensors are used to detect gases. Composition and content sensors.
Gas detectors can detect gas leakage, and remind people to take safety measures such as evacuation, forced ventilation, and shutdown of equipment by sending out sound and light alarm signals. It is an indispensable instrument in industrial production and daily life.
But the gas detector is not always able to accurately measure the gas concentration, just like our watch needs to be calibrated regularly and the standard time, the gas detector also needs to be calibrated regularly to ensure the accuracy of the detection, and the calibration process is called for "calibration".
The accuracy of the combustible gas alarm is an important prerequisite for detecting and issuing an alarm, and its accuracy depends on the built-in combustible gas sensor. Whether it is an electrochemical sensor or a catalytic combustion sensor, it will be affected by certain environmental conditions during use. Due to the influence of substances, it gradually changes or even becomes invalid due to poisoning. Only through timely maintenance and calibration can the accuracy of the results detected by the instrument be guaranteed.
