  alpha DO2000 1/2 DIN Series Dissolved Oxygen Analyzer/Controller


Incorporating the superior Galvanic oxygen probe, operating the alpha DO 2000 controller is immediate.  With the Galvanc probe, there is no start-up or 'warm-up' time.  The probe only takes 40 to 50 seconds to attain 95% of actual readings.  Calibration is quick and easy using the atmospheric air as the calibration media for 100% air saturation.
