Dissolved Oxygen Sensors - Greenspan DO100, DO3000

The Greenspan Analytical Dissolved Oxygen Sensors provide accurate long-term measurements under a wide range of environmental conditions.

The patented Australian CSIRO diffusion cell technology developed by Greenspan Analytical, provides a simple, effective and robust means of obtaining continuous in-situ dissolved oxygen measurements with minimum maintenance requirements.

A combination of membrane and sensor technology characterise the design of the design of this sensor.  A new generation chemical sensor provides inherently greater stability than conventional polarographic technology.  Compared to conventional membrane designs, the large surface area of the diffusion membrane substantially reduces errors caused by surface contamination. It has temperature compensation to provide true output in ppm of dissolved oxygen of percent saturation.
