Tips: Precautions for carbon dioxide gas detector calibration.

The calibration personnel must be trained, understand the principle and performance of carbon dioxide gas detector, be proficient in operating skills, and hold a certificate.
The adjustment personnel must strictly follow the operating procedures.
CO₂ gas detector must be measured and appraised and can be used only after it is qualified.
Before calibrating the carbon dioxide gas detector, perform a visual inspection. Calibration can be started after confirming the appearance is intact.
CO₂ gas detector that needs to be calibrated should be warmed up for about 20 minutes. Zero the carbon dioxide gas detector in fresh air.
After the zero adjustment is completed, pass a standard gas sample with a concentration of about 1.0% according to the flow specified in the manual. Calibrate the displayed value of the carbon dioxide gas detector. The indicated value is consistent with the standard gas value and can be used after it is stable.

Existing reviews of Fixed Carbon Dioxide (CO2) Gas Detector, 0 to 9999 ppm

Working environment of gas detector

Hi, I was wondering if the handheld carbon monoxide (CO) gas detector would work in a hydrogen rich environment?

From: Hart | Date: 27/09/2021

Was this review helpful? Yes No (0/0)

ATO Responded

Generally, H2 and CO gases interfere with each other, and all sensors in the market can not do measurement without some little interference. But our gas detector sensor is of high quality, and the relative interference will be much smaller.

Questions about gas detection

I have one more question about the calibration of H2S gas. Do I need to have pure H2S gas or mixture of H2S CH4 also work?

From: Lxxv | Date: 06/09/2021

Was this review helpful? Yes No (0/0)

ATO Responded

Yes, for the calibration of H2S gas, it can use pure H2S gas (As long as the concentration of H2S does not exceed the gas detector) or mixture of H2S+CH4, both are ok.
