pH 2000 Advance 1/2 DIN pH/ORP PI Controller

Receive the most efficient use of costly chemicals and reagents with the advanced control functions of the pH 2000 PI controller. This controller offers sophisticated operating features in a rugged housing suitable for wall, panel or pipe mounting.

Select from several control types: on/off control, proportional pulse length, proportional pulse frequency or PI (proportional integral) control. Proportional integral control lets you fine-tune controller to prevent overshoot and provide tight control.


Controller features two-point pH calibration with automatic or manual buffer recognition of a wide range of buffer sets. Select asymmetrical input for standard applications symmetrical input for applications with high electrical noise.

Control Features:

  • Programmable for on/off, proportional, or PI (proportional integral) control—ideal for the most demanding process applications
  • Two programmable relay outputs plus separate alarm relay
  • Separate electrode wash contact relay to control electrode cleaning systems
  • Hold feature lets you connect flow or level switches to protect your pump
  • Separately adjustable high and low set point hysteresis bands prevent rapid contact switching near set points

Advanced Functions:

  • Symmetrical mode operation eliminates electrical noise problems when used with solution ground
  • Two galvanically isolated, scalable 0-20/4-20 mA outputs for pH/ORP and temperature
  • Push button two-point calibration and online electrode offset adjustment
  • Two level password protection prevents tampering with settings

Physical Features:

  • Universal power supply input from 80 to 250 V ac/dc allows use at multiple sites and in areas with fluctuating voltage
  • Backlit display offers easy reading in low-light conditions
  • Large dual LCD shows pH (or mV) and temperature simultaneously
  • Rugged NEMA 4X housing protects your controller from the elements and dirty industrial applications
  • Nonvolatile memory maintains setup if power fails
