Panel-Mount Dual Output pH Controller - Auto-diagnostic feature
- Two models to choose from
- Isolated recorder output
This instrument allows the selection of two setpoints with two independent outputs for acid and alkaline dosages. The self-diagnostic features verify the calibration values ( offset and slope) and the electrode status. The alarm interval can be set to activate the alarm when the measured value differs from the setpoint more than the selected tolerance (0.1 to 3 pH). Two versions are available: HI 8711E with direct input signal from a pH electrode and HI 8711T with analog input from a transmitter. The output configuration for connecting a recorder or a PLC can be chosen between 0-20 or 4-20 mA. The front panel is protected behind a transparent splash-proof cover.
The HI 8711 series is supplied complete with mounting brackets and instructions. |
