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 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.

Thermo Scientific Alpha pH 2000 Wall Mount/Panel Mount pH/ORP Controller/Transmitter

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.

Product Features With a wide measuring range of 0 to 20 ppm or 0 to 200 % saturation, Alpha DO 2000 controller/transmitter is ideal for use in a variety of applications, ranging from water treatment and monitoring to pharmaceutical and food processing. Meter comes in both Galvanic and Amperometric versions. ::Readings values in mg/L or % air saturations, selectable from menu options ::Quick, easy calibration using atmospheric air as calibration media for 100 % air saturation ::Pressure, Salinity and Automatic Temperature Compensation The Galvanic Electrode (ECDOGEN-S & ECDOTPII-S) Rugged and long-lasting, the galvanic electrode requires no warm-up time and prevents zero drift by recreating H2O within the electrode. This prevents change of pH to the electrode and allows it to recycle within the probe. The result: galvanic sensors have long lifespans and require low maintenance costs. The Amperometric Electrode (EC237150 & EC237450) The amperometric dissolved oxygen electrode contains special membranes that are designed to require almost zero maintenance. These unique membranes stay stable even under harsh ambient conditions and high pressure. This enables the sensors to capture accurate DO readings within short response time at required flow as low as 0.02 m/s.
