Honeywell UDA2182 Dual Loop Analyzer Controller

Honeywell's UDA2182 series is a versatile dual-input analyzer that measures pH/ORP, contacting conductivity, and dissolved oxygen. The mix-and-match design enables inventory reduction, as well as easy field modification of inputs for a wide range of applications. The UDA2182's common form factor provides quick retrofit of existing panels and installations.

Key Specifications

  • Single or Dual Input Analyzer
  • Mix and Match Process Measurements on One Analyzer: pH, ORP, Conductivity, TDS, and Dissolved Oxygen
  • Wireless Infrared Port for Setup via Pocket PC. (Same Hardware/Software as Honeywell UDC Controllers)
  • Graphic LED Displays Entire Status at a Glance
  • Direct replacement for retired Honeywell (L&N) 7082, Honeywell 9782P/C, and Honeywell 7021/7022 Models.
