HI8710 is a panel mounted pH controller with self-diagnostic test capabilities. Users can set: the setpoint for acid or alkaline dosage, the tolerance of the setpoint before an alarm is activated, the dosage mode: automatic, continuous on or OFF and the over dosage control by setting the overtime dosage knob.
Hanna’s exclusive Fail Safe Alarm System protects against problems caused by power supply failure or signal interruption. An alarm condition is indicated by a red LED, located directly on the front panel of the controller.
“Overtime dosage” function with selection knob and jumper for disable on the rear panel. If the dosing relay remains continuously activated for more than selected dosing time the alarm relay is activated, the alarm LED is blinking and the dosing relay is deactivated.
When used in conjunction with the HI8720 ORP controller, the ORP Dosing Consent Device function will ensure that the ORP dosage will start only when the pH level is correct.
A 2-wire Pt100 can be connected to provide automatic temperature compensation of the pH measurements.
Supports potential matching pin connection to avoid typical problems caused by grounding loop current, such as progressive damage of the electrode, fluctuating measurements, and poor process regulation.
A removable, transparent splash-proof cover protects the front panel.
