Product Description
PI-3675 pH/ORP 2-point Controller in NEMA 4X Enclosure
Documentation
- Two set point with 2 independent dosing or alarm outputs, one for acid and another for alkaline dosage, or one for acid dosage and another for alarm control, or one for alkaline dosage and another for alarm control.
- Two relays may be used for pH control to manage both acid and base injection in order to maintain pH with a specified range. ORP reads in 1mV resolution and us used to control an Oxidation or Reduction reaction typically for Chlorination, De-chlorination, Cyanide Oxidation or Chrom Reduction.
- 3675-pH/ORP model accepts direct input from a pH or ORP electrode and is in a 1/4 DIN Panel Mount enclosure. It provides a dual point simultaneous control of Acid and Alkaline. It offers great flexibility and convenience with its user friendly format and easy access buttons. Its design has high reliability and accuracy, with 5 amp relays, and allows 110VAC/220VAC selection.
- 3675-pH/ORP is enclosed in a NEMA 4X weatherproof box in a wall mount format.
- Accepts direct input from an electrode
The 3675-pH/ORP offers great flexibility and convenience with its user friendly format and easy access buttons. It's advanced design has high reliability and accuracy, with 5 amp relays, and allows 110VAC/220VAC selection.
