Product Features
 
 > Seven ranges in a single controller allows the     controller to be used in a wide variety of     applications with the maximum range at 1000     mS/cm
 > User-Customization through Advanced Setup     Menu offers flexibility in matching the     controller's functions to suit individual's     specific requirement
 > Choice of 4-cell or 2-cell electrode system
 > Programmable for On/Off, Proportional, or PI     (Proportional Integral Control) - ideal for most     demanding precision process control     applications
 > Backlit Display offers reading in low-light     conditions
 > Universal Power Supply Input from 85 to 250     VAC/DC allows use at multiple sites and     withstands voltage fluctuations
 > Two Galvanically Isolated Scaleable 0-20/4-20     mA Outputs for Conductivity and temperature
 > Wash Contact Relay controls electrodes     cleaning systems at desired duration and     frequency
 > Adjustable Hysteresis (Dead Band) prevents     rapid contact switching near set point
 > Non-Volatile Memory retains all stored     parameters and calibration data even if power     fails
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 to recorder to document data for regulatory compliance.
