TAN + BN Test Kit
Portable Mini-Lab for testing Lubricants
The GESERCO TAN + BN Test Kit is a true portable
lubricant analysis mini laboratory.
The TAN + BN Test Kit is a stand-alone solution
designed for monitoring on the operation site
two main characteristics of the lubricant:

The lubricant acidity TAN
The lubricant alkaline reserve (BN)

The tests are simple and rapid, and the kit
includes a detailed testing and interpretation
guide so that the engineer can make
immediate decisions for maintaining the
lubricated equipment and increasing its
lifespan.

Acidity – TAN Test
Acid lubricants are the source of numerous
potential machinery failures through:

Corroding of metallic components

Gumming and clamping of lubricated parts

Production of glaze and sludge in the
circuitry
The GESERCO TAN Test provides a quick and
accurate method for determining the lubricant
Total Acid Number.

Alkaline Reserve – BN test
The alkaline reserve formulated into engine oils
neutralizes the acids produced by the
combustion of fuels containing sulphur. In
service, the BN of lubricating oils will fall from its
original value.
GESERCO
BN
Test
provides
accurate
measurement of the remaining oil alkaline
reserve (BN) within minutes.

It consists in adding various reagents to the oil in
order to induce a change of colour. The
volume of reagent required for changing the
colour is precisely monitored and allows
calculating the TAN value in mg kOH/g.

The measurement method consists in adding
some reagent to the oil sample which will
produce a pressure proportional to the
alkalinity reserve of the oil.
The produced pressure is measured by means
of a dial pressure gauge.
