DONALDSON'S new portable fluid analysis kit allows operators and inspectors to easily conduct on-site particulate and water analysis. Using the patch test method, the kit allows for the quick and reliable assignment of a three-digit cleanliness code per ISO 4406-1999 to a given fluid sample. Samples are collected in a 25 ml fluid sample bottle through a patch membrane filter. The kit gives users an excellent visual representation of the contaminants in the oil, and the test can be conducted in as little as 10 minutes.
