A clean lubricant is essential in hydraulic systems. These operate with extremely tight tolerances and high pressure, which makes them susceptible to small amounts of contamination. The pollution that is generated by solid wear particles, water, gases and high temperatures are the main causes of the deterioration of these systems. It is also known that most hydraulic failures are caused by aqueous or solid contamination of the fluid.

Hydraulic lubricant analysis is essential for preventing system failure. It is recommended to establish a program of basic routine tests, which are contained in the TRIBO 1 package. In the case of having systems more susceptible to humidity, the TRIBO 2 package is recommended, it contains the Karl Fischer test, which gives results Accurate% or ppm humidity for deeper control.
