Protos II 4400
Product Overview
Protos II 4400 (X) is a flexible, 4-wire device that can be used when measuring pH, ORP, conductivity (conductive or inductive), and oxygen. As one of the most versatile products in the Knick family, it allows for monitoring and controlling processes even in the most complex applications such as hazardous areas. In addition, Memosens® digital, analog, and other digital sensors can be connected.
When using Memosens digital sensors the Protos II 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.
