Oil Tester RTK Retrofit-test-kit

To refit an refrigeration system to use R134a, the mineral oil must be rinsed out and replaced with a suitable ester oil. This rinsing process must ensure that the system contains as little mineral oil as possible. The RTK Retrofit Test Kit provides you with a simple yet precise method to determine if enough mineral oil has been removed. The test is based on a comparison of a sample of used oil from the system with a sample of unused oil. If the mineral oil content is too high, it will visibly precipitate. 3 simple steps are needed to determine if the mineral oil content is above 5%, between 1 and 5% or below 1%. The test kit contains 2 bottles with testing fluid and 3 pipettes.
