8 and pH below 6. The second level can then be an alarm at pH=9. With such a system it is not necessary to make frequent checks and calibrations, however we recommend an annual or biannual check of the calibration. Instructional manual- HBPH-MK2 – UK-004 Page 4... -
Page 5: Calibrating The Sensor
The operation of the 2-wire, 4-20 mA sensor can be checked by a few simple measurements. Two pH buffer solutions, 7 pH and either 4 pH or 10 pH, and a DC milliammeter are required. Instructional manual- HBPH-MK2 – UK-004 Page 5... -
Page 6: Probe Cleaning
5. Soak the probe for not more than 5 minutes in the chosen acid; then rinse thoroughly with clean warm water and soak in water for 3-5 minutes. 6. Calibrate the system in accordance with the instrument instruction manual. Instructional manual- HBPH-MK2 – UK-004 Page 6... -
Page 7: Replacement Of Salt Bridge
Replacement of Salt Bridge If the system cannot be calibrated after cleaning the probe, it may be necessary to replace the standard cell solution and/or the salt bridge. A salt bridge kit is available from HB Products for this purpose. -
