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.
