HI8711 allows the selection of two set
points with two independent outputs
for acid and alkaline dosages.
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 ampli*ed electrodes. In
addition, you can choose the output
con*guration for connecting a recorder
or a PLC, between 0-20 or 4-20 mA.
The HI8711 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.
A removable, transparent splash-proof
