Citadel CT-ETH

The CITADEL CT-ETH incorporates proven inductively coupled conductivity sensor technology with a thermistor.

Data is output continuously via RS-232 or RS-485. All CT-ETH sensors are for mounting thru-hull of a vessel, in the flow, with no pumps or other artificial flushing devices required. Precise internal fixed references provide continuous calibration for increased long-term reliability.?
