  • Page 27: General Calibration & Maintenance Procedure

    6. GENERAL CALIBRATION & MAINTENANCE PROCEDURE 6.1 Calibration for pH measurement To calibrate the FU20 pH/ORP 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.

  • Page 28: Maintenance Of The Fu20 Sensor

    6.3 Maintenance of the FU20 sensor A pH sensor requires routine maintenance to keep the measuring elements clean and functioning. Depending on the process, different cleaning solutions may be required. Avoid cleaning the complete sensor with solution. Some cleaning solutions will damage the model code sticker and connector which are placed on top of the sensor.
