UltraPreciWaterTest ® - PreciWaterTest ®
Water Content Measurement Apparatus
Conforms to ISO9114 :1997*

The
GESERCO
UltraPreciWaterTest®
and
® apparatus allow for accurate
PreciWaterTest
and cost-effective measurement of the water
content in any little volatile liquids.
They are applicable to measuring water in:
Mineral Oils and Petroleum Products
(Motor Oils, Fuels, Brake Fluids, Gearbox
Oils, Solvents…)
Synthetic Oils and Synthetic Lubricants
Bio Diesels, Bio Oils and Bio Lubricants
Vegetable Oils
Aromatic liquids
Alcohols
Soluble Solid Products (Greases…)
The water content measurement is simple and
easy to perform within minutes.

Measurement Principle
Both
the
UltraPreciWaterTest®
and
the
PreciWaterTest® use a reacting measurement
method:
A sample of liquid to be tested is placed in a
closed reaction flask and a chemical reactant
is added.
Any water contained in the tested sample
combines with the reactant and produces gas.
The volume of generated gas is precisely
proportional to the amount of water contained
in the tested sample.
The volume of gas is measured by means of a
graduated liquid column gauge.
