It has proven to be crucial to ensure accurate detection of gas concentrations in the environment. The difference between theoretical and actual values ​​can be large. Therefore, it is recommended to use standard gas calibration equipment or send the instrument to a local third-party measurement and calibration institution for calibration verification.
If the gas sensor is used for a long time, the measured value may have errors and need to be calibrated. After calibration, if the detection is still inaccurate, you must confirm with the manufacturer whether the gas sensor can continue to be used. If a sensor is nearing the end of its useful life, it may still experience inaccurate measurements and noticeably drifting values ​​over time, even if it is recalibrated and functioning properly for a short period of time. Therefore, it is recommended to contact the manufacturer and replace the gas sensor.
In summary, it is crucial to ensure accurate measurement of gas concentrations. Proper calibration and maintenance of gas sensors is critical to ensuring accurate readings. If in any doubt, it is best to contact the manufacturer or a reputable third party agency for verification and calibration.
