Product information "HI 8710 pH Analog Controller with Self-Diagnostic Test"

 

  • Inputs: BNC connector,  Direct wire connection with amplified probe (supports HI 1006 series probes) and 4-20 mA from a transmitter
  • Extended temperature compensation  range: -20 to 100°C
  • Supports potential matching pin connection
  • Both 4-20 and 0-20 mA output
  • ±5V outputs for amplified electrodes
  • Backlit LCD
  • Auto-diagnostic tests for pH electrode and instrument status
  • Operational mode LED indicators
  • Fail Safe Function–the alarm relay is activated at power down
  • Transparent splash-proof cover

 

HI 8710 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.

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.

“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.

* ORP dosing consent device
