The product is Kolor Kut Gasoline Gauging Paste, a specialized color-change indicator used to accurately measure fuel levels in storage tanks.
Key Features and FunctionPurpose: It is designed to determine the depth of various hydrocarbons, including gasoline, diesel, kerosene, crude oil, and jet fuels.
Color Change: The paste is originally light pink and turns bright red instantly upon contact with hydrocarbons, providing a clear visual mark at the fuel-air interface.
Application: It is typically spread in a thin layer on a dipping tape, gauging rod, or measuring stick before it is lowered into the tank.
Limitations: It is less effective with alcohols because they evaporate quickly, which can cause the paste to return to its original color.
