alpha-TDS190 1/8 DIN Total Dissolved Solids Controller with Temperature Display and Transmitter

alpha TDS190 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.

Product Features

::	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 with scrolling, 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

TDS 190: Ideal for drinking water, monitoring and control, hydroponics and aquaponic solution balance and control, pools and spa hardness and salinity control.
