Par-Test is a complete laboratory analysis, performed on a small quantity of fluid, used to indicate the sources and quantity of contamination. The test results are very comprehensive, including the following critical analysis:

Spectrochemical analysis

of over 20 wear metals and additives.

Particle count

reported over five size ranges. The particle count is expressed as an ISO cleaniness code. It is also plotted on a graph for better comparisons.

Viscosity at 100^oF

reported in centistokes.

Water content

is expressed as a % of volume. Many hydraulic systems may tolerate up to 300 ppm(.03%) of water contamination. Some bearing or lube oil systems must strictly limit water content.

Analysis recommendations

summarizes results and indicates action to be taken to prevent problems.

Individual bottles include instructions for sampling and are self-addressed. Test results are mailed back to you within 24-48 hours.
