Alpha RES 1000 Resistivity Controller/Transmitter
- High Accuracy Superb accuracy delivered across 2 resistivity ranges
- Warranty This product is covered by 1 year warranty
- Versatile Can be used in a variety of applications
Overview
If you are looking for a resistivity controller/transmitter which offers high accuracy of ±1% across 2 ranges the Eutech Alpha RES 1000 resistivity controller/transmitter is the perfect choice. This controller/transmitter offers adjustable temperature co-efficient from 0.0 to 10.0% this ensures higher accuracy, a pure water compensation option is inbuit for added accuracy in specific applications making this device suitable for a wide range of applications. Selecting the pure water compensation option corrects non-linearity of pure water temperature correction curves in ultrapure water applications.
The Alpha RES 1000 meter clearly displays electrode information after each successful caibration and previous data is saved for the convienience of the user. This meter is handily equiped with alarm delay and individual set-point hystereses to prevent chattering, false alarms and the need for down time.
Galvanically isolated and scaleable 0/4 to 20 mA output for high quality output on peripheral devices is the perfect feature to make this controller/transmitter the perfect choice for resistivity measurements.
