WSDO2001 is a dissolved oxygen sensor designed specifically for high temperature use. It can withstand steam sterilization up to 130 °C.

It uses the Polarography Principle, where the electrodes are polarized by a constant voltage. Oxygen present in the water body diffuses through the membrane and gives up its electrons. This electrical change is detected and converted to DO readings.
