1. PREFACE 1.1 Introduction This instruction manual provides information for the installation and use of the SC25V, combined 12mm glass sensor; pH, Ref, LE and Temperature. The SC25V is the best choice for the majority of typical processand waste water applications. The sensor is designed with titanium liquid earth, increased electrolyte reservoir and large surface area PTFE diaphragm combined with a long pathway inner junction resulting in a longtime stability and prolonged lifetime. 1.

3. INSTALLATION SC25V 3.1 Typical installation The SC25V sensor can be installed in-line, in a bypass loop or in an immersion assembly. For best results the SC25V should be mounted with the process fluid flowing towards the sensor and positioned at least 15° above the horizontal plane to eliminate air bubbles in the glass bulb. See fig. 6 section 3.3 3.2 Preparing the sensor for use Remove the sensor from its shipping box and slide off the “wet pocket” (the flask including the rubber ring).

GENERAL CALIBRATION AND MAINTENANCE PROCEDURE 5.1 Calibration for pH measurement To calibrate a pH sensor, at least two buffer solutions with known pH values are required. It is recommended to use one buffer solution with a value of pH=7. The second buffer solution should be either acidic (pH<7) or alkaline (pH>7), depending on the process value to be measured.
5.3 Chemical cleaning HCN The chemical cleaning system is effective in processes where deposits can be removed by a suitable solvent. Good cleaning effects can be obtained from periodically spraying of an electrode. EXA PH450G has a built-in wash timer with programmable wash time, interval time and relaxation time for automatic cleaning of the electrodes, preventing pollution of the pH sensitive parts. After washing, it is possible to check the response time of the electrodes.
