BPD17 pH/ redox (ORP)
• Differential Input for excellent noise rejection
• Accepts pH glass and redox (ORP) electrodes
• Able to display the pH reading and electrode mv value
• Dose alarm timer prevents overdosing
By providing the user with the flexibility to select either a pH or redox (ORP) input and operating with a single ended or differential input, means a single instrument may be used for the majority of pH and redox (ORP) applications.
Temperature compensator selection of Pt1000 or Pt100 allows the instrument to be used with
almost any pH electrode system.
Two digital inputs are provided for remote activation of user defined operations. The functions available are offline, interlock, flow switch input and tank level switch. This causes any active set points to de-energise and the current output to change to its offline status.
Both measurement inputs and current outputs can be individually calibrated from the front panel.
For applications requiring accurate measurements it is possible to calibrate the instrument and sensor to either a standard solution or a titrated solution concentration. An off-line facility allows the instrument to be adjusted without disturbing external processes.
For applications which require automatic sensor cleaning, set point relays can be configured as a clean initiator.
The clean duration, recovery time and interval period are all programmable. During the clean and recovery periods the instrument will go off-line and hold the current outputs and disable the control relay
