Eutech pH 200 Controller

Scrolling, 14-segment LED guides user through set-up functions

  Two set point, two SPDT relay for on/off control
  Reliable power supply from 85 to 250 V AC/DC withstands voltage fluctuations
  Two separately adjustable hysteresis bands prevents rapid contact switching at either set point
  Selectable symmetrical mode operation eliminates electrical noise
  Two-point pH calibration; offset ORP and temperature calibration
  4-20 mA output for remote monitoring or hard copy recording
  Two level password protection for calibration and setup parameters
  Toggle between pH (or mV) and temperature display
  Removable terminal strips offer quick and easy connections
  Battery back-up of memory maintains set-up if power fails

These sturdy, compact controllers withstand voltage fluctuations from 85 to 250V AC/DC! They are ideal for installation were electrical fluctuations are common, or install them 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, 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.
