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.
