General Description   Online water treatment controller   Online water treatment controller
Interface   Backlit dot matrix LCD
  Seven-segment LCD
Measuring parameters
  pH
ORP
Chlorine

(user can choose only to measure one parameter at a time - with the appropriate probe connected).

  Conductivity
Measuring ranges   pH:  0 - 14
ORP:  -1000 to +1400 mV
Chlorine:  0-2, 0-20, 0-200 ppm
  0-2,000 µS
(microSiemens)
Output relays   Two output relays:
Both relays are set and operated totally independent of each other.

Relay 1:  Has its own set point, with option to power on above or below its set point.

Relay 2:  Has its own set point with option to power on above or below its set point (totally independent of Relay 1's settings).

Relays are dry contact, but a simple jumper from the power terminal can be done to provide power.
