AquaMetrix Shark-120 Controller/Analyzer for pH, ORP, Conductivity, and Flow

Water Analytics has annoucement the retirement of the AquaMetrix Shark 120 effective September 1, 2016. Please see the AquaMetrix 2250 controller for a suitable replacement.

Aquametrix Shark multiparameter controller/analyzer lets you choose any combination of pH, ORP, conductivity, or flow parameters to manage from a single, flexible, easy-to-use unit.

The Shark controller/analyzer comes standard with two isolated, independent, scalable 4-20 mA outputs and two control relays standard. Control relays can be used for rising or falling process, with easy-to-program on/off setpoints, and each has a built-in independent cycle timer with field-set on/off times to help reduce chemical overshoot. A third relay is set as an alarm by default, but can be used as a third control relay, with both high and low adjustable on and off setpoints.

Key Specifications

  • One model for managing pH, ORP, conductivity/resistivity and flow
  • Two control relays with with third relay for high/low alarm
  • Large bright LED front-face display and interior LCD menu for configuration
  • Reduces chemical consumption with cycle timed relays
  • NEMA 4X polycarbonate enclosure with flip-down front panel
  • Can be surface-, panel-, or pipe-mounted
