S411 DIG N Datasheet
The S411 DIG/N digital conductivity electrode provides reliable conductivity measurement thanks to the use of a 4-electrode graphite sensor. It communicates measurements via the MODBUS RTU protocol and features an integrated temperature sensor.
The sensor S411 DIG/N is used for the digital measure of conductivity in pure and process waters.
The S411 DIG/N Electrode is suitable for conductivity measures in various applications. It is compatible with firmware starting from 50XX8PW5.
