alpha-CON190 1/8 DIN Conductivity Controller with Temperature Display and Transmitter

alpha CON190 with improved user interface enables user to gain direct access to calibration mode with CAL key and allows quick set point adjustment with SP1 and SP2 keys.

Quick Set Point Adjustment - SP1 and SP2 keys allow user to adjust set points easily
Direct Access to CAL Mode - enables user to enter calibration mode with a simple key press
User-Customisation through scrolling Menu, 14-Segment LED - intuitive user interface guides user easily through setup functions
Multi Measurement Range- User Selectable
Galvanically Isolated 4-20 mA Output for remote monitoring or hardcopy recording
Universal Power Supply Input from 85 to 250 VAC/DC allows use at multiple sites and withstands voltage fluctuations
Automatic Temperature Compensation with 3-wire Pt 100 system ensures accurate readings under fluctuating temperatures
Adjustable Temperature Coefficient (0 to 5.0%/^oC) and selectable cell constants for more accurate measurements
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
Easy Installation and Wiring with detachable plug-in connectors

Applications

CON 190: Use for plating tank, rinse water, boiler and cooling tower, feed water and blowdown control, font solution make-up and control for printing, photographic developing, chemical production process, ion exchange systems, R.O. systems, industrial process water, wastewater, dilute acids, salts and bases.
