Water Treatment Process
Control Instrumentation / SCADA Interface : Water Quality pH Meter
(Alpha PH2000)
Our water treatment process control pH meter /
SCADA Interface is widely used by water companies in the
UK for water quality control. The Alpha 2000 can be easily configured to your SCADA
at the touch of a button! it has two Galvanically Isolated Scaleable 0-20/4-20 mA Outputs for pH/ORP and
temperature, making it simple to configure to your SCADA,
remote SCADA system or any other control device. The Alpha 2000 is
our top of the range industrial pH process control instrument that
is proving to be very successful within the water industry when used
with our spi11 Porous Teflon pH probe with built-in Pt100/Pt1000
temperature compensation, especially in troublesome applications
such as low conductivity of water. The user can also hook the
instrument to recorder and document data for regulatory compliance.
Applications for the Alpha 2000 include:
Water Treatment : 
Water Treatment, Water Purification, Drinking
Water, Sewage Treatment, Effluent treatment and Waste Water Treatment.
General :
Process Analytical Technology
Industrial :
Food Processing, Waste Chemical Disposal, Aquarium,
Pharmaceutical and Hydroponics
Regulatory :
Hook to recorder to document data for regulatory compliance.
Main Features :
- Built-In Programmable for On/Off, Proportional, or PI
(Proportional integral control) - ideal for most demanding
precision process control applications
- User-Customization through Advanced Setup Menu offers
flexibility in matching the controller's functions to suit
individual's specific requirement
- Automatic Calibration with Auto-Buffer Recognition eliminates
mistakes during calibration
- Symmetrical Mode Operation eliminates electronic noise
problems when used with solution ground
- Backlit Display offers reading in low-light conditions
- Universal Power Supply Input from 85 to 250 VAC/DC allows use
at multiple sites and withstands voltage fluctuations
- Rugged NEMA 4X housing protects controller from the elements
and dirty industrial applications
- Two Level Password Protection prevents unauthorized tampering
with settings0 to 2000 Second Time Delay Adjustment on control
and alarm delays
- Hold Relay for use with float switches/flow switches and other
controllers as a failsafe function
- Two Galvanically Isolated Scaleable 0-20/4-20 mA Outputs for
pH/ORP and temperature
- Wash Contact Relay controls electrodes cleaning systems at
desired duration and frequency
- Choice of Glass or Antimony Electrode for general purpose or
hydrofluoric acid applications
- 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
- Large Dual Display shows pH (or ORP) with temperature
simultaneously - features clear multiple icons, set points, and
status messages
- Choice of Temperature Sensor Pt100/Pt1000 with 2-wire or
3-wire temperature input selection
- Easy Installation and Wiring with detachable plug-in
connectors
- Panel-mounted version is also available
