The EC102 is an online conductivity and resistivity meter for high-purity water. With a 0.01 cell constant it reads resistivity up to 18.25 MΩ·cm, which makes it suitable for pharmaceutical purified water, EDI outlets, mixed-bed polishers and laboratory ultrapure water systems. Higher cell constants extend the same meter to RO, cooling and process water up to 20,000 µS/cm.

Salinity and TDS display modes, an isolated 4–20 mA output and optional isolated RS485 Modbus RTU make it easy to integrate into an existing water system PLC.

Typical applications

Pharma purified water (PW) and WFI pre-treatment
EDI and mixed-bed outlet monitoring
Two-pass RO permeate
Power plant DM water and condensate
