Overview
HK-3240 Apparatus for Undissolved Water in Aviation Turbine Fuels conforms to ASTM D3240 Standard Test Method for Undissolved Water In Aviation Turbine Fuels. A measured sample of fuel is passed through as uranine dye-treated filter pad. Undissolved (free) water in the fuel will react with the uranine dye. When the pad is subsquently illuminated by ultraviolet (UV) light, the dye previously contacted by free water will fluoresce a bright yellow with the brightness increasing for increasing amounts of free water in the fuel. The UV light-illuminated pad is compared to a known standard using a photocell comparator, and the free water in the fuel sample is read out in parts per million by volume. By varying the fuel sample size, the range of the test method can be increased.
