Water Quality Controllers

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 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 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-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 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
