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.
When used in conjunction with the HI8720
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.
A removable, transparent splash-proof
cover protects the front panel.
