Thermo Scientific Alpha pH 2000

Thermo Scientific Alpha pH 2000

Product Features
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.
The Alpha pH 2000 is user-friendly and intuitive: controller alerts when meter or electrode requires maintenance, and provides trouble-shooting prompts in plain language.
::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
  
::Quick, easy push-button calibration with auto-buffer recognition. Meter displays electrode status after each calibration
  
::Accepts Antimony electrodes – useful in applications involving Hydrofluoric (HF) Acid
  
::Control and measure pH and ORP simultaneously with master-slave operation by placing two controllers side by side
Asymmetrical
Asymmetrical mode works well in environments with where there is little or no electrical noise. When there is electrical noise, the noise acts as a common signal and is picked up by both the pH and the reference electrodes. However, since the reference electrode is grounded to the ground potential of the amplifier, electrical noise will be present only on the pH electrode. This noise is amplified along with the pH signal, which causes reading fluctuations in an electrically noisy atmosphere. Electrical noise from a DC source (as in an electroplating tank) will typically result in stable but incorrect values.
Symmetrical
Symmetrical mode avoids grounding the reference electrode by reconfiguring the input to a floating differential mode. The electrical noise appears equally on the pH and reference electrodes, and is therefore rejected by the operational amplifier.
The Alpha pH 2000 transmitter offers an option for Symmetrical Mode of Operation. To take advantage of Symmetrical operation, you must have an electrode with a solution ground (potential matching) pin. If your electrode does not have a solution ground, be sure to set the controller to Asymmetrical mode.

Applications
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.
