Water Quality Controllers

The AM-2250 provides control of external devices using its 3 independent control and alarm relays. Select the parameter you wish to measure. Conductivity, pH, ORP or Flow.

The PHCN37 pH panel mounted controller features automatic or manual temperature compensation of pH, two 5 amp mechanical relays and a choice of a scalable 4 to 20 mA output

The PHCN-961/962 series of pH controller and transmitter provides a reliable method of monitoring and controlling pH in water treatment and chemical industries

The CDCN-91 dual channel conductivity/resistivity controller is a two-channel input device equipped with three scalable 4 to 20 mA outputs and four programmable relays.

The CDTX-111 and CDTX-112 conductivity/temperature controllers are panel instruments for in-process monitoring of conductivity that use unique signal collection technology.

The CDCN-961 conductance, resistance or total dissolved solids (TDS) controller is designed for inline monitoring of process solutions and water applications.

The AM-2251 is a new addition to the 2250 family. Select the parameter you wish to measure from the LCD menu on the inside front cover. Choose Conductivity, pH, ORP or D.O.

The PHCN-85 has two 4 to 20 mA outputs to control or retransmit the pH or ORP and temperature value. In addition there are 3 relay outputs for pH, ORP, temperature or timing

Toroidal Conductivity or Concentration Analyzer. Discontinued. Replaced by AM-2251
