Thermo Scientific Alpha RES 1000
Resistivity Controller/Transmitter

 


Product Features

The Alpha RES 1000 offers high accuracy across 2 resistivity ranges with adjustable temperature
co-efficient and pure water compensation option. Controller/ transmitter is equipped with alarm delay and individual set-point hystereses to prevent chattering, false alarms, and uncecessary
down time.

:: ±1% full scale accuracy across two Resistivity ranges
   
:: Adjustable temperature coefficient from 0.0 to 10.0 % for higher accuracy
   
:: Pure water compensation option corrects non-linearity of pure water temperature correction curves in ultrapure water applications
   
:: Option of Auto or Manual Temperature Compensation. Three-wire system compensates for cable-length resistance errors
   
:: Meter displays electrode information after each successful calibration. Previous calibration data is retained in the event of unsuccessful calibrations
   
:: Galvanically-isolated, scaleable 0/4 to 20 mA output for high-quality output on peripheral devices

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.
