WSDO4051 is a dissolved oxygen sensor which has been improved from the previous designs. Featuring a stainless steel grit mesh membrane instead of the standard silicone diaphragm membrane.

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.
