Thermo Scientific Alpha pH 2000D Wall Mount Differential pH/ORP Controller/Transmitter

Product Features
The Alpha pH 2000D Controller/Transmitter and combination electrode system employs differential pH measurement technology.

What’s unique about this system is the differential electrode, which uses a pH glass bulb in place of the conventional reference system, making it more resistant to contamination or fouling in harsh wastewater applications. Replaceable salt bridge and reference solution add lifespan to the electrode when junction clogs.

The result: a reliable, long-lasting and cost-saving pH measurement system for demanding environments.

:: Wide pH range of -2.00 to 16.00 pH at two-decimal accuracy

:: ORP mode measures in mV or % concentration, with independent calibration modes

:: Control and measure pH and ORP simultaneously with master-slave operation by placing
two controllers side by side

:: Wall mount, pipe mount or panel mount options. Compact design of electrode with universal 1.5” NPT mounting threads enables optimal mounting positions
The pH Differential Electrode:

:: Cost Savings, Reduced Downtime and Maintenance Costs – soiled salt bridge and buffer reference solution can easily be replaced at a fraction of the cost of a new combination electrode

:: Automatic Temperature Compensation
– built-in temperature electrode

:: Use Any Buffer Standard from 2 to 10 pH as a Reference – very useful for applications that require adjustable isopotential points

:: Built-In Electronic Amplifier provides a low impedance output from the electrode, and allows analyzers to be located up to 3000 feet away from the electrode

:: Ground Rod Minimizes Electrical Interference from motors, pumps, transformers and ground currents


General: Useful for any batch or on-line type application that requires accurate pH or ORP control.

Water Purification/Treatment: Use for batch and on-line control of incoming process water, rinse water treatment, recirculating system and waste water treatment.

Industrial: Ideal for chemical processing, food processing. aquarium, pharmaceutical, hydroponics and waste control industries.

Regulatory: Hook to recorder to document data for regulatory compliance.
