The carbon dioxide detector should be used in places with many water vapor and water droplets (relative humidity at 90%). Otherwise, if the water vapor is too high for a long time, the carbon dioxide sensor will be damaged.
2. The calibration and calibration personnel must be trained, understand the principle and performance of the instrument, be proficient in operating skills, and hold a certificate for work.
3. The instruments used must be qualified after measurement and identification.
4. After the carbon dioxide detector alarms, do not turn on the electrical switch; confirm the cause of the high carbon dioxide concentration, and deal with it in time: if the cause is unknown, please contact the relevant gas department for a thorough inspection.
5. Check the appearance of the instrument before calibrating the instrument, and the instrument can be used only after the appearance of the instrument is intact.
