Overview

Eutech's Alpha DO 2000 Dissolved Oxygen Controller/Transmitter is ideal for use in a wide range of applications ranging from water treatment and monitoring of pharmaceutical and food processing. The Alpha DO 2000 meter displays values in mg/L or % air saturation's both are selectable from the easy to use menu options, and comes in both Galvanic and Amperometric versions. Calibration is a quick and easy process using atmospheric air for 100% air saturation.

The Galvanic Electrode option is rugged and long lasting and requires no warm-up time and prevents zero drift by recreating H20 within the electrode. This action prevents change of pH to the electrode and allows it to recycle within the probe. The end result is the galvanic sensors have long lifespans and require low maintenance costs.

The Amperometric dissolved oxygen electrode option contains special membranes that are designed to require almost zero maintenance. The brilliance of theses unique membranes is they stay stable even under harsh ambient conditions and high pressure. The result is this enables the sensors to capture accurate DO readings within short response time at required flow as low as 0.2m/s.

This product is covered by a one year warranty.
