ABSTRACT:
A field test kit which uses a single vial is useful in testing acidity in refrigeration oils contaminated with a colored leak detector. This vial contains a pre-measured indicator solution and has sufficient additional volume that the test oil can be added directly to the indicator solution and accurately measured within the vial. After shaking, the mixture quickly separates into two phases. The color of the bottom phase indicates whether or not the acidity of the refrigeration oil exceeds 0.05 acid number.
