Q45C2 2E Resistivity Transmitter

Our 2-Electrode Resistivity Transmitters

work best with these applications:

Reverse Osmosis Systems

Boiler Feed Water

Pharmaceutical Water

Deionization Systems

Return Condensate

Semiconductor Water

Desalination Systems


Our 2-Electrode Resistivity Transmitter provides the reliable and accurate low-level measurements required for such high-purity water systems. Monitors provide large, easy-to-read LCD displays with a second display line for indication of temperature or other operational information. For those applications where results in resistivity units are preferred, Q45C2 monitors can be programmed to display readings in Meg-ohm units instead of microSiemens.


The transmitter employs 2-Electrode conductivity sensors with low cell constants to provide continuous water quality measurements from 0-20 to 0-2,000 microSiemens. The 2-Electrode sensors are specifically designed for use in ultra-pure water and nonfouling applications. The sensors are available in several mounting configurations including 316SS compression fittings or sanitary-style. These sensors may also be mounted submersion-style or in a hot-tap configuration.
