GoTest Test Kit
Portable mini-laboratory for testing Diesel oils
The GESERCO GoTest Test Kit is a true portable
Diesel Oil analysis mini laboratory.
The kit is designed for monitoring on site three main
characteristics of Diesel oil and verify the conformity of
the oil to its specifications:

Water content
Viscosity
Density

The tests are simple and rapid, and allow the
engineer to make immediate decisions for
maintaining the lifespan of the Diesel engine.

Viscosity

Water in Diesel Oil

Test Principle
The test uses a model VCD3T falling ball
viscometer which allows for instant comparison
of the Diesel oil viscosity with Reference
Standards
of
minimum
and
maximum
acceptable viscosity.
The user will then know quickly and simply if the
Diesel oil is within acceptable limits.
The kit is delivered with Reference Standards to
NF EN 590*.

Test method
The measurement method consists in adding
some reagent to the oil sample which will
produce a pressure proportional to the amount
of water contained in the oil.
The produced pressure is measured by means
of a dial pressure gauge.
The dial gauge is graduated with %H2O values,
allowing for direct read-out of the %H2O
measurement.
