Description
Discontinued, replaced by either CDCN-961-Controller Or AM-2250-Controller
.
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 ON-OFF 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.
