For oxygen sensors/analyzers to make precise measurement, calibration using standard gases is necessary. Zero point adjustment is performed using the air as reference, and precision calibration is performed by comparing the output voltage and the theoretical value using three or more standard gases. (Standard gases used for calibration: 100% O2, Air, N2 balance 1000ppm O2, N2 balance 1% H2, N2 balance 0.1% H2, etc.) Our company has established the highest level of sensor calibration system in Korea, and conducts precision tests using standard gases to issue test reports. We also provide precision calibration for products in use on customer sites as well as field inspection services. |
