  • Page 25: General Calibration & Maintenance Procedure

    6. GENERAL CALIBRATION & MAINTENANCE PROCEDURE 6.1 Calibration for pH measurement To calibrate the SC25V sensor, two buffer solutions with known pH values are required. It is recommended that one buffer solution has a value near to pH 7.00. Depending on the process value to be measured, the second buffer solution should be either acidic (below pH 7.00) or alkaline (above pH 7.00).
