The pH scale ranges from 0 to 14pH - where 0pH is acidic and 14pH is alkaline. pH is temperature dependent thus the temperature of the sample under test will affect the pH value recorded.
The Elcometer 148 sensor has automatic temperature compensation, ensuring like-for-like measurements can be taken for meaningful comparison of the results.
The condition of the sensor is automatically monitored after each successive calibration and sensors can be easily replaced by the user as and when required.
STANDARDS:ASTM E 70
