Control Instruments : Conductivity / Total Dissolved Solids (TDS) :
Industrial Online Conductivity / TDS
Monitor / Controller (Alpha CON200)
Our competitively priced Alpha 200 Process Control
Conductivity / Total Dissolved Solids meter
shares many of the advanced features of the Alpha 2000 and 1000 units,
as with the Alpha 1000, The Alpha CON200 has
Galvanically Isolated 4-20 mA Output also Two Level Password
Protection preventing un authorized tampering with settings.
Applications for the Alpha
200 include:
Conductivity :
plating tank, rinse water, boiler and cooling tower, feed water, photographic developing, chemical production process, ion
exchange systems, R.O. systems, industrial process water,
wastewater, dilute acids, salts and bases.
Total Dissolved Solids :
drinking water, monitoring and control, hydroponics and aquaponic
solution balance and control, pools and spa hardness and salinity
control.
Main Features :
- 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
- Two Level Password Protection prevents un authorized tampering
with settings
- Automatic Temperature Compensation with 3-wire Pt 100 system
ensures accurate readings under fluctuating temperatures
- Adjustable Temperature Coefficient (0 to 10%/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
