alpha-pH1000 1/4 DIN pH/ORP Controller

  • Built-In Programmable Limit, Proportional (Pulse Length or Pulse Frequency) - ideal for precision process control applications

  • User-Customization through Advanced Setup Menu offers flexibility in matching the controller's functions to suit individual's specific requirement

  • Automatic Calibration with Auto-Buffer Recognition eliminates mistakes during calibration

  • Symmetrical Mode Operation eliminates electronic noise problems when used with solution ground

  • One-Point Online Calibration without shutting down the line

  • Hold Relay for use with float switches/flow switches and other controllers as a failsafe function

  • Two Level Password Protection prevents un authorized tampering with settings

  • 0 to 2000 Second Time Delay Adjustment on control and alarm delays

  • Two Galvanically Isolated Scaleable 0-20/4-20 mA Outputs for pH/ORP

  • Wash Contact Relay controls electrodes cleaning systems at desired duration and frequency

  • Choice of Glass or Antimony Electrode for general purpose or hydrofluoric acid applications 

  • Adjustable Hysteresis (Dead Band) prevents rapid contact switching near set point

  • Non-Volatile Memory retains all stored parameters and calibration data even if power fails

  • Large Dual Display shows pH (or ORP) with temperature simultaneously - features clear multiple icons, set points, and status messages 
  • Choice of Temperature Sensor Pt100/Pt1000 with 2-wire or 3-wire temperature input selection
  • Easy Installation and Wiring with detachable plug-in connectors

Applications

General: Useful for any batch or on-line type application that requires accurate pH or ORP control.

Water Purification/Treatment: Use for batch and on-line control of incoming process water, rinse water treatment, recirculating system and waste water treatment.

Industrial: Ideal for chemical processing, food processing. aquarium, pharmaceutical, hydroponics and waste control industries.

Regulatory:
Hook to recorder to document data for regulatory compliance.
