Product Features

v	Ten Selectable Conductivity Measurement Ranges in one controller via its IP54 front panel. High-level accuracy of ±1% of full scale can be obtained with appropriate cells and correct temperature coefficient

v	User-Customization through Advanced Setup Menu offers flexibility in matching the controller's functions to suit individual's specific requirement

v	Choice of Cell Constant (0.01, 0.1, 1.0, 10.0) for accurate control in any solution

v	Hold Relay for use with float switches/flow switches and other controllers as a failsafe function

v	Two Level Password Protection prevents un authorized tampering with settings

v	0 to 2000 Second Time Delay Adjustment on control and alarm delays

v	Galvanically Isolated Scalebale 0-20/4-20 mA Outputs

v	Wash Contact Relay controls electrodes cleaning systems at desired duration and frequency

v	Adjustable Hysteresis (Dead Band) prevents rapid contact switching near set point

v	Non-Volatile Memory retains all stored parameters and calibration data even if power fails

v	Line Resistance Compensation against intrinsic cable resistance for longer cable connection

v	Large Dual Display shows measurement with temperature simultaneously - features clear multiple icons, set points, and status messages

v	Choice of Temperature Sensor Pt100/Pt1000 with 2-wire or 3-wire temperature input selection

v	Easy Installation and Wiring with detachable plug-in connectors

Applications

General: Use for virtually any batch or online applications where rapid, accurate control. Great for OEM/system integrator.

Industrial: Use in applications involving agriculture, chemical processing, boiler and water heaters, wafer-fab, microprocessor manufacturing, pharmaceuticals, pulp and paper industries, and bleach manufacturing.

Water Purification/Treatment: Use to treat batches of incoming process water, ultrapure water, boiler and feed water control.

Regulatory: Hook up to recorder for regulatory compliance data collection.
