ST-ATCPHMEAS - REV 0416 - Automatic Temperature Compensation and pH Measurement

This article discusses Automatic Temperature Compensation (ATC) in pH measurement. ATC improves accuracy by adjusting electrode calibration for temperature variations and is recommended to avoid errors from temperature differences. ATC does not adjust sample pH to a standard temperature like 25°C. An ATC probe is beneficial, but manual temperature compensation is possible though less convenient. Despite theoretical assumptions, ATC is more accurate than non-compensated measurements
