This instrument allows the selection of a setpoint for oxidizing or reducing dosage. It is provided with self-diagnostic feature to control the calibration at 0 and 500 mV. The user can also set the tolerance of the setpoint (10 to 200 mV), before an alarm is activated.
When used in conjunction with the HI 8710 pH controller, the ODCD* function (featured by the HI 8710) will ensure that the ORP dosage will start only when the pH level is correct.
These instruments have been designed for easy and fast installation, and are provided with membrane keypads on the front panel, large display and autodiagnostic functions.
All connections are made through screw terminals on the rear panel.
Each model accepts either a direct input from a pH or ORP electrode or from a transmitter through 4-20 mA input. The instrument also provides ±5V power output and input terminals for amplified electrodes.
The HI 8720 incorporates adjustable overtime dosing protection from 5 to 60 minutes. If dosing exceeds selected time, the alarm will be triggered and the dosing contact will deactivate. This feature can be activated or deactivated via a shorting connection on the rear panel.
Moreover, you can choose the output configuration for connecting a recorder or a PLC, between 0-20 or 4-20 mA.
The front panel is protected behind a transparent splash-proof cover.
