Thermo Scientific Alpha pH 2000D

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.

Wide pH Range - Measures from -2.00 to 16.00 pH with two-decimal accuracy

Dual Mode Operation - ORP mode measures in mV or % concentration, with independent calibration modes

Master-Slave Operation - Control and measure pH and ORP simultaneously by placing two controllers side by side

Flexible Mounting - Wall mount, pipe mount or panel mount options with compact design and universal 1.5” NPT mounting threads

Cost-Effective Maintenance - Soiled salt bridge and buffer reference solution can easily be replaced at a fraction of the cost of a new combination electrode

Built-in Temperature Compensation - Automatic temperature compensation with built-in temperature electrode

Flexible Reference Standards - Use any buffer standard from 2 to 10 pH as a reference, ideal for applications requiring adjustable isopotential points

Enhanced Signal Processing - Built-in electronic amplifier provides low impedance output, allowing analyzers to be located up to 3000 feet away

Noise Reduction - 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 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.
