Panel-Mount pH Controller - Single set point with selection of acid or alkaline dosage
- Two models to choose from
- Isolated recorder output
This instrument allows the selection of a setpoint for acid or alkaline dosage. The user can also set the tolerance of the setpoint (0.1 to 3 pH), before an alarm is activated. When used in conjunction with the HI 8720 ORP controller, the ODCD* function will ensure that the ORP dosage will start only when the pH level is correct. Two different versions are available to accept either a direct input from a pH electrode (E version) or from a transmitter through 4-20 mA input (T version). The output configuration for connecting a recorder or a PLC can be chosen between 0-20 or 4-20 mA. The controller is also provided with a unique self-diagnostic test to check the pH electrode and instrument status. The front panel is protected behind a transparent splash-proof cover.
The HI 8710 series is supplied complete with mounting brackets and instructions. |
