Honeywell APT2000 Analytical Process Transmitters

Honeywell's analytical process transmitter (APT)2000 is a two-wire, 24-volt device that continuously measures pH, ORP, or conductivity in industrial processes. The water-and corrosion-resistant IP65-rated enclosure meets the measurement needs of intrinsically safe, non-incendive, and general-purpose areas.

You can use Honeywell sensors, as well as a wide variety of competitor electrodes, as inputs to the APT2000. The APT2000 comes standard with a 4-20 mA output and can be equipped with the HART communications protocol for bi-directional remote monitoring/control of the process.

Key Specifications

  • Large Display with Easy-to-Read 0.75" Measured Value
  • Simple Operator Interface with Pictographs
  • HART Bi-Directional Communications Protocol
  • Diagnostics for Monitoring Calibration, Probe, and Transmitter Self-Test
  • Works with Honeywell pH/ORP Electrodes and Conductivity Cells
  • Manual Loop-Back Check for Integrity of 4-20 mA Output Signal
  • Wall, Pipe, or Panel Mount in Both Safe and Hazardous Areas
