Ištirpusio deguonies transmiteris Thermo Scientific Alpha DO2000
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.
The Galvanic Electrode 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 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. |
Applications
General: Useful for monitoring temperature and control of DO in wastewater treatment and aquaculture applications. Use with valves, blowers or aerators to ensure proper system operation.
