  • Page 27: General Calibration & Maintenance Procedure

    6. GENERAL CALIBRATION & MAINTENANCE PROCEDURE Calibration of the FU20-FTS/MTS sensor has to be done with the pH analyzer connected. Normally the pH standards that are preprogrammed in the pH analyzer can be used for calibration with the pH analyzer set to “AUTOCAL”. The FU20-FTS/MTS however is a differential pH sensor which needs pH buffers that have the same ionic strength because the sodium reference will change as the ionic strength changes.

    Instruction Manual of the analyzer. The rH value is a function of the reference system and the pH value of the buffer solution. The FU20-FTS/MTS sensor has a reference system of 1molal Silver/Silver Chloride (Ag/AgCl). The commonly used standards for ORP and rH calibration are made from Chinhydron (Quinhydrone) powder dissolved in pH buffer solutions (1g / 200 ml).
