pH 200 1/8 DIN pH/ORP Controller

These sturdy, compact controllers withstand voltage fluctuations from 85 to 250 V ac/dc! They are ideal for installation where electrical fluctuations are common, or in series throughout areas of differing electrical conditions.
Advanced setup mode lets you set relay values, select pH or ORP control, select manual or automatic temperature compensation (ATC), and more. It also lets you view electrode slope and offset, and previous calibration points.
The 1/8 DIN housing is ready to install in standard panels and NEMA rated boxes. Includes mounting hardware; accepts electrodes with BNC connectors and 100 Pt RTD ATC elements.

Control Features:

  • Two set point, two SPDT relay for on/off control
  • Two separately adjustable hysteresis bands prevents rapid contact switching at either set point

Advanced Functions:

  • Selectable symmetrical mode operation eliminates electrical noise
  • Two-point pH calibration; one point calibration for temperature and ORP
  • View previous calibration points and electrode slope/offset
  • 4-20 mA output for remote monitoring or hard copy recording
  • Two level password protection for calibration and setup parameters

Physical Features:

  • Scrolling, 14-segment LED guides user through setup functions
  • Reliable power supply from 85 to 250 V ac/dc
  • Toggle between pH (or mV) and temperature display
  • Removable terminal strips offer quick and easy connections
  • Nonvolatile memory maintains setup if power fails
