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 such as Biodiesel, diesel, gasoline, SVO, glycerine, polyalkalene glycol, and brake fluid 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.
The part number for the Analog Water Test Kit is 01-WTK-DELUXE. It has an analog gauge and contains the water test vessel, one bottle of Calcium Hydride (Reagent A), Reagent B (3 pints), a 10 and 30 milliliter syringe, wash bottle, safety glasses, box of disposable gloves, and instructions.

The part number for the Digital Water Test Kit is 01-WTK-DELUXEDP. It has a digital gauge and contains the water test vessel, one bottle of Calcium Hydride (Reagent A), Reagent B (3 pints), a 10 and 30 milliliter syringe, wash bottle, safety glasses, box of disposable gloves, and instructions.
Principle of Operation
The Water Test Kit consists of three components: the test vessel, Reagents A & B. Reagent A is calcium hydride which is classified as Dangerous Goods (HazMat). Reagent A reacts instantaneously with water to produce hydrogen gas. The pressure developed in the test vessel is directly proportional to the water content of the sample. Because the water test kits contain Reagent A, we are restricted in how we can ship the kits and replacement bottles of Reagent A.
