Page 3: Introduction
1. Introduction pHX / ReX are used to measure pH or Redox potential in water and wastewater treatment plants and other industrial applications. 2. A few words about this manual This manual details installation procedures and operational features of the Cerlic pH and Redox sensors. -
Page 4: Unpacking The Sensor
Damages If damages occurred during shipment, immediately contact UPS or other truck line as well as your Cerlic representative. The shipment can be returned only after contact has been made with Cerlic. Packaging The original packaging is designed to protect the equipment and should be used for storage or if the goods must be returned. -
Page 5: Installing The Sensor
6. Installing the Sensor The sensor is installed with the enclosed mounting brackets, which are screwed onto the wall of the flume or tank (see figure 1). An optional adjustable slide rail holder is available. The electrode should be placed deep enough so that it always stays in the measuring media, even when the level varies (see figure 1). -
Page 6: Connections
Connections Connect the sensor to the BB2 central unit using the attached cable. If needed, the cable can be extended using extension cables. Several sensors can be connected to one BB2 using Y-splitter or junction box. See “Technical description” for details. Installation hints •... -
Page 7: Mounting The Electrode
8. Mounting the electrode In order to mount an electrode the sensor must be opened in both ends. At the cable end, the electronics of the sensor is mounted to the black PVC-top. Care must be taken in order not to damage the circuit board. Both ends are easiest opened by carefully turning and pulling at the same time. -
Page 8: Cleaning
Mounting plate for cleaning solenoid valves To provide an easy mounting of solenoid valves for the built-in flushing nozzles Cerlic offers a predrilled Aluminum handrail mounting plate. The Mounting plate is fixed to the rail using two u-bolts. -
Page 9: Maintenance
10. Maintenance pHX / ReX sensors are easy to maintain. An electrode maintenance schedule should be kept, listing when it is removed and cleaned. When this is done, the electrode should be checked against a known buffer solution. If the control value does not match, a re- calibration should be made. -

Page 15: Calibration
13. Calibration The sensor is shipped pre-calibrated, but since all electrodes are different, the sensor must be calibrated with its electrode to give a good measurement. The electrode degrades by time and calibrations shall be done regularly following a maintenance schedule. -
Page 16: Adjusting Orp
• If smart calibration is used and BB2 recognizes the buffer, BB2 will suggest a pH value showing the text ”Accept smart calibration pH X.X”. You can choose to accept the value or to change it manually. • If manual calibration is used BB2 will always ask for the value of the buffer, enter the value and press ENTER. -

Page 22: Appendix 3, Ph Temperature Dependency
At pH 7 or 78°F the temperature error is zero. If temperature or pH changes the temperature eror is calculated using the following formula: 0.03 pH-difference / pH / 10°C. pHX has a built in compensation for the temperature error provided that the correct temperature of calibration buffers and measured media is entered.. -
