Teledyne- CITADEL CTD-ES

Published on : Tuesday 30-11--0001

The CITADEL CTD-ES incorporates proven inductively coupled conductivity sensor technology with a platinum resistance thermometer and micromachined silicon pressure sensor to provide highly accurate and stable readings.

Data is output continuously via RS-232 or RS-485. All Citadel CTD-ES sensors are mounted in the flow, with no pumps or other artificial flushing devices required. Precise internal fixed references provide continuous calibration for increased long-term reliability

 

Key Features:

• Non-electrode ceramic inductive conductivity sensor

• High measurement accuracy without the need for pumps

• Lightweight yet durable construction

 

Applications

• Environmental Monitoring

• Ocean Observing Networks

• Climate Change Research
