Online pH /
Redox(ORP) Monitor
/ Controller (Alpha PH200)
Our competitively priced Alpha 200 Process Control pH
/ Redox (ORP) meter
shares many of the advanced features of the Alpha 2000 and 1000 units,
as with the Alpha 1000, it has the advantage of being Panel Mountable and is ideal for
such applications as pH control in fume cupboards or where a panel
mountable meter is required. The Alpha pH200 has
Galvanically Isolated 4-20 mA Output also Two Level Password
Protection preventing un authorized tampering with settings. Applications for the Alpha
pH200 include:
General : 
Ideal for virtually any batch type application where pH or ORP
control or adjustment is needed. Use as ORP monitor for ozone
systems and general purpose pH monitor for all types of water
treatment and chemical processes.
Aquaculture :
Use for pH or ORP control in fish ponds and tanks.
Industrial :
Use to treat batches of incoming process water, rinse water
treatment, recirculating system and wastewater treatment. Suitable
for pH or ORP control of plating tanks and chemical processing
tanks. Ideal for low cost monitor with alarms for batch and process
applications. Perfect for wastewater neutralization in small and
medium sized batches
Main Features :
- User-Customisation through Scrolling Menu, 14-Segment LED -
intuitive user interface guides user easily through setup
functions
- Symmetrical Mode Operation eliminates electronic noise
problems when used with solution ground
- 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 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
