pH Analog Controller with Self-diagnostic test
The HI 8710 is a panel mounted pH Controller with self diagnostic and test. The user can set: the setpoint for acid or alkaline dosage, the tolerance of the setpoint before an alarm is activated, the dosage mode: automatic, continuous in or OFF and the over dosage control by setting the overtime dosage knob.
Key features Backlit LCD Operational mode LED indicators Transparent splash-proof cover Fail Safe Function - the alarm relay is activated at power down
