⻬ Analyzer/Transmitter/Controller ⻬ Self-Guided Menu ⻬ Auto-Range Scales ⻬ Automatic Calibration and Check ⻬ Recognizes Standard and Cell ⻬ Automatic Temperature Compensation ⻬ On-Off/PWM Control ⻬ Programmable Transmitter Output ⻬ RS485 Output

The CDCN441 conductance/resistance analyzercontroller is designed for online monitoring of process solutions and water applications. Applications include: waste water treatment, power plants, thermo electric plants, pharmaceutical, photographic industries and soft drinks industries. The menus are self guiding with simple three button programming. Available control outputs include ONOFF or pulse width modulation. The transmitter output is also programmable from the keypad eliminating the need for potentiometer or dip-switch settings. The calibration function automatically recognizes the cell used and the buffer solution resulting in a simple and straight forward system calibration.

Equipment is built with solid state technology, electronic contacts and not electrical contacts, avoiding mechanical movement and off course no sparks.
