Water or moisture is the second largest contamination (after particles) in oil systems with damaging effects on the life time of both the machinery and the oil.

The amount of water a specific oil type can dissolve varies significantly, depending on e.g. the base oil, additives, oxidation, temperature and other factors. The WIO sensor detects the amount of water, before the damage. 

The sensor is simple to install and easy to connect. It provides a measurement range of 0.01-1.00aw, with accuracy of ±0.03aw and a resolution of better than 0.004aw.
