Honeywell DirectLine pH and ORP Sensor Modules

Honeywell's DirectLine electronics module will change the way you measure pH (DL421), ORP (DL422), conductivity (DL423) and dissolved oxygen (DL424, 425)! Each module is packaged in an industrially rugged enclosure that can be mounted integrally to your electrode, or remotely mounted for easy access. Just add a sensor and mounting, and you're ready to go!

Key Specifications

  • A Fraction of the Cost of Standard Analyzer/Cable/Sensor Configurations!
  • Local Display and Keypad for Easy Setup, Calibration, and Operation
  • Built-In Diagnostics for Electronics and Sensor Reduce Troubleshooting
  • Sample or Auto Buffer Options for Fast Calibration
  • Direct 4-20 mA Output!!! No Need for Dedicated Analyzer or Transmitter
  • Sensor Can Be Safely Removed and Replaced Without Cycling Power
