alpha-RES1000 1/4 DIN Resistivity Controller

Product Features

::	Two Selectable Resistivity 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

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

::	Choice of Cell Constant (0.01, 0.1) for accurate control in any solution

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

::	Two Level Password Protection prevents un authorized tampering with settings

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

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

::	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

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

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

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

::	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.

Water Purification/Treatment: Suitable for pure, ultrapure, and reagent grade water batches of incoming process water.

Regulatory: Hook to recorder to document data for regulatory compliance.
