Diesel/Biodiesel Fuel Field Test Kits

Field test kits for diesel and biodiesel fuel to help determine the quality of fuel where it matters most. They help prevent costly repairs to equipment due to the presence of contaminants such as water and glycerin.

We have a range of kits suitable for several applications, details of which are below. If you have a different application that you can’t see listed, please do contact us.


VFT-0100: Water and Visual Clarity
This is a simple two-part test in which diesel or biodiesel fuel is tested for visual clarity and the presence of entrained (undissolved) water

How It Works
Visual clarity testing will often reveal particulates such as sediment, glycerin, or microbial residue. In the second part of the test, a vial of water detection fluid is added to the fuel, allowing the detection of entrained water to as low as 100ppm. At 500ppm, the detection fluid leaves a distinct red ring at the bottom of the sample bottle.

When to use it
As an initial screening test for fuel deliveries and for periodic monitoring of fuel quality at the dispenser and storage tanks.
It can also be used as a vehicle maintenance diagnostic to detect entrained water, a major cause of blown injector tips.



VFT-0145: Glycerin Field Test
This is a test for the presence of glycerin in fuel, providing results within the range of 0.05% and 0.5% of mass for biodiesel fuel. It is an enzymatic test that has a greater than 99% correlation with the ASTM methods and it can be used for pure biodiesel and biodiesel blends.

How it works
Glycerin is a by product of biodiesel production and should not be present in the final product (the ASTM specification for B100 is 0.24% of mass). Glycerin is known to be harmful to diesel fuel systems and engines.

When to use it
This test should be used as an initial screening test for fuel deliveries and for
periodic monitoring of fuel quality at the dispenser and storage tanks. It can also be used to screen tactical
(emergency) vehicles and generators for the presence of biodiesel fuel. 



VFT-0150: Bio-Detect Field Test Kit
The Bio-Detect Field Test detects the presence of biodiesel in standard (petroleum based) diesel fuel. It detects biodiesel at levels as low as 1% (B1) and can be used as a pre-screening test for tactical vehicles such as emergency vehicles, aircraft, or in military applications.

This test is also used as part of standard vehicle maintenance to indicate whether biodiesel fuel quality testing is required.
