The DSI Field Industrial Oil Analysis Test Kit is a portable field test kit that combines the tools needed to easily and quickly test three key parameters of conventional and synthetic lubricating oils.

The Water-in-Oil DIGI Cell quickly tests for water in all types of conventional and synthetic oils using a non-HAZMAT reagent for lower shipping costs and portability.

The rugged patch test apparatus reliably identifies hydraulic particles contamination and abnormal wear on-site in industrial, fleet, marine and off-highway equipment.

The Visgage© checks viscosity of all ranges of oils without thermometers or stop watches to assure quality control in your on-site oil analysis program.

Included is a HiVac oil sampling pump with six bottles, a steel-clad thermometer that reads from 14 F to 230 F(-10 C to 110 C) and tempilstik indicators used to define upper and lower limits of a location's operating temperature.
