Protos II 4400
Modular 4-wire, Multi-parameter Transmitter

Protos II 4400 (X) is a flexible, 4-wire transmitter for pH, ORP, conductivity, and oxygen. Protos II allows for monitoring and controlling processes even in complex and hazardous area applications.

  • Mix and match measuring, control, and communication modules
  • Intuitive user interface guides users through menus and provides measurement and troubleshooting tips
Description

The Protos II 4400 is the most versatile of all transmitters in the Knick product family. The analyzer connects to Memosens® digital, analog, and ISM/other digital sensors for pH, ORP, conductivity (conductive or inductive), and oxygen.

When using Memosens digital sensors the Protos II 4400 can accept up to four parameter inputs in any combination. A variety of digital protocols are available along with the standard 4…20 mA and relay outputs. Protos II can be used for PID control.

The convenient and simple operation of Protos II guides users through all menus and provides error messages and troubleshooting tips on a clearly organized display. When using the Protos II with EtherNet/IP or PROFINET, process control systems can cost-effectively manage predictive maintenance while utilizing measured values and sensor diagnostic data from the transmitter.
