ABSTRACT:
A method for determining the presence of water in an organic test fluid including the steps of admixing a portion of the organic test fluid with a liquid indicator system containing a non-polar solvent which is soluble in the organic test fluid, and comprises a petroleum distillate. The solvent also includes a non-hazardous water soluble dye which will evidence a color change upon direct contact with water. The mixture is agitated to permit intimate contact between the indicator system and the organic test fluid. The mixture is then allowed to stand for a period in which the dye will react with any water contained in the organic test fluid, and provide a color indication thereof.
