- accurately determine the water content of diesel, biodiesel, petrol, hydraulic oil, engine oil and vegetable oils.

Water in lubricating fluids can cause serious damage to machinery with premature failure of bearings, gears, pistons and other components. Major bearing manufacturers claim that as little as .05% water in the oil will reduce bearing life by as much as 60%.

Until now, there hasn't been an easy and convenient way to determine water content on-site. Samples have always been sent to the lab while the people in the field waited for the test results. Now, the Water Test Kit can be used to determine the percentage of water in various fluids right at the machinery's location. Test results are available in as little as five minutes. Typically these fluids are hydraulic fluids, gear oils and other circulation system lubricants. Not only can these fluids be tested, but others can also be tested. The maximum range of the gauge is 1.5% water, but lower or higher concentrations (.50% or 50% Full Scale) can be tested using the laboratory techniques listed in the operating manual.

With a resolution of 0.001% (10 PPM) water, any fluid can be tested as long as the following conditions are met:

A. The water must be in the form of free molecules or droplets and not be chemically or physically bound as in an emulsion.

B. The fluid should not attack the water vessel components which are anodized aluminum and brass.

C. Most importantly, the fluid testing must not have a flash point below 60°C.
