PRODUCT OVERVIEW

Understand the instrument

The TDS210-B converts a compatible electrode signal into a local reading and process output. Electrode constant determines the usable conductivity range. The controller provides temperature compensation, isolated current output and Modbus communication, with relay outputs for control or alarm tasks.

KEY FEATURES

Designed for the task

EC, TDS and resistivity measurement
Selectable electrode constants
Automatic or manual temperature compensation
Two relay outputs
