Degassed Cation Conductivity System

New product
More info

The METTLER TOLEDO Thornton DCC1000 System offers a new design for conductivity measurement for power cycle chemistry monitoring. By providing conductivity measurement in compliance with ASTM D4519, this system provides assurance of water purity to maximize power production and minimize corrosion. Unambiguous measurement of trace levels of corrosion-causing contaminants is enabled with minimal operator supervision.

Advanced Transmitter Design
The M800 Transmitter provides flexible touchscreen color display options including single-screen, simultaneous display of all conductivity, calculated pH and temperature measurements plus trend graphs for all parameters. Intelligent Sensor Management automatically interfaces with sensors, ensuring correct calibration data for each sensor is used.

Efficient Cation Exchange
The small diameter, ASTM D4519-compliant cation resin cartridge in the DCC1000 optimizes ion exchange kinetics to achieve lower, more accurate readingsthan systems with larger cartridges that allow ionic leaching. More accurate readings enable faster plant startups and more readily meet turbine warranty requirements.

Highest Accuracy Digital Measurements
Digital UniCond® conductivity sensors achieve the highest available accuracy,enabled by simultaneous calibration of cell constant, temperature element and internal measuring circuit, with results stored in on-board memory. This self-contained measurement is impervious to external error sources.

Features and Benefits

Precise detection of corrosive contaminants for faster plant start-ups and simpler turbine warranty compliance
Multi-parameter M800 transmitter with single-screen display of all measurements for easy displaying and monitoring of sample conditions
Integrated flow sensor with automatic heater shut-off if flow stops to protect the DCC1000 system from thermal damage and maintenance
