MicrobMonitor2® TEST KIT

MicrobMonitor2® Test Kit is IATA approved and recognized by major airframe manufacturers for aviation fuel and is easy to use. You can test the water or fuel phase of aviation fuel. The kit consists of a test bottle containing a nutrient gel that promotes the growth of bacteria and yeast/molds. Once a sample has been added to the bottle, the container is incubated as instructed, dark place for 1 to 4 days for bacteria and 3 additional days for yeast & mold. The microbes actually grow in and on the gel. They will show up as red or purplish red dots in the sample bottle indicating a positive result. If you require a quantitative number there is a color chart to compare the results against.


Generally any positive growth requires action. Call FQS to consult on possible treatment options.


The MicrobMonitor2® can be used to test both the fuel/oil phase and the water phase.
