Built for the rugged industrial environment, the Alpha pH 2000 transmitter comes with an option for symmetrical mode of operation, making it ideal for electrically noisy environments. IP65 NEMA 4X casing is weatherproof and corrosion-resistant, protecting meter against harsh elements.
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
Smart Calibration - Quick, easy push-button calibration with auto-buffer recognition and electrode status display
Antimony Electrode Support - Accepts Antimony electrodes for applications involving Hydrofluoric (HF) Acid
Master-Slave Operation - Control and measure pH and ORP simultaneously by placing two controllers side by side
Intelligent Diagnostics - Controller alerts when meter or electrode requires maintenance with trouble-shooting prompts in plain language
Symmetrical Mode Option - Ideal for electrically noisy environments, using floating differential mode operation
Asymmetrical Mode Works well in environments with little or no electrical noise. When there is electrical noise, the noise acts as a common signal and is picked up by both pH and reference electrodes. Since the reference electrode is grounded to the amplifier’s ground potential, electrical noise appears only on the pH electrode, causing reading fluctuations. DC source noise (e.g., from electroplating tanks) typically results in stable but incorrect values.
Symmetrical Mode Avoids reference electrode grounding by using floating differential mode. Electrical noise appears equally on pH and reference electrodes and is rejected by the operational amplifier. Requires an electrode with solution ground (potential matching) pin.
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.
