Process Control Instruments : Resistivity : Industrial Online Resistivity Monitor / Controller for pure, ultrapure, reagent grade water and batches of incoming process water.

Our Alpha RES1000 Resistivity controller is ideal for pure, ultrapure, and reagent grade water and batches of incoming process water. The meter can be customised by the user through it's advanced setup menu offering flexibility in matching the controller's functions to suit individual's specific requirements. The user has the ability to measure 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 some of the features offered from the Alpha RES1000 include : 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 and the choice of two Galvanically Isolated Scaleable 0-20/4-20 mA Outputs for use with your SCADA or other control devices.

Applications for the Alpha RES1000 include :

General : 

Use for virtually any batch or online applications where rapid, accurate control is required. 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.
