Applicable standard: ASTM D7843

A1390 Varnish Tendency Index Tester is suitable for the determination of colored insolubles in turbine oil. It monitors and evaluates the tendency of turbine oil to form oil film, avoiding the deposition of varnish that affects the heat dissipation of equipment, leading to accelerated aging of the oil and reduced lubrication performance.
