Now you can use the same kit commercial Biodiesel producers use to measure the percent of water in any liquid sample with extreme accuracy. This industrial quality tester allows you to quickly and accurately identify just how much water content is in a sample of any oil feedstock or finished biodiesel sample.

How It Works
The test works by placing a sample of fluid into the testing unit and then adding a reacting agent. The tester is then sealed and within a few minutes the test is ready to read. The tester works by causing a chemical reaction to occur between the water in the test sample and the reagent. The reagent converts the water to hydrogen gas which gives off pressure. The amount of pressure given off directly correlates to the percentage of water in the sample.

Testing Range
This great tester can read anywhere from .005% (50 PPM) to over 50% (500,000 PPM) using the techniques found in the manual. There's a series of 5 different ranges that can be used to measure across so the test is extremely versatile. Test results can be read in as little as 5 minutes and are extremely accurate.

Portable, Small, & Easy To Use
Because the test kit is comprised of just the tester, some reagent, and dry solvent, it can be used out in the field or in any test lab and because the results are so accurate you can be sure you're adjusting your Biodiesel production recipes accurately.

Why Test For Water Content?
Water is problematic in the biodiesel production process for many reasons. If it's present in the starting feedstock it can hinder a successful reaction thereby causing unreacted fuel to be produced. By knowing what the water percentage is prior to making biodiesel, certain counter measures can be used to either eliminate the water from the feedstock or compensate for it being there.

Within the ASTM Specification for biodiesel (ASTM D-6751), there's also a requirement for a maximum water percentage in the finished biodiesel. If the percent of water is over this limit the biodiesel won't meet the ASTM specification and shouldn't be introduced into the market place.

By conducting a simple water test on the feedstock, you'll know where you're starting and what steps may be necessary to deal with any water content. Then, after you've produced the biodiesel, you can check the finished biodiesel for water content again to ensure it meets the ASTM guideline. If it doesn't, appropriate "drying" measures can be used to bring the biodiesel into specification.

The deluxe kit comes with everything you'll need to perform 50 quick water tests.
