BNTest™ Test Kit with ROTG
Determination of the Base Number of Motor Oils
The GESERCO BNTest™ test kit allows for simple,
fast and cost effective determination of the
alkaline reserve (BN) of motor oils and for
monitoring the BN depletion rate over time.
The GESERCO BNTest™ test kit comes as a light
and strong kit which can be used on site by any
non-specialized operator.
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's state of the art Rapid Oil Test Gauge
provides accurate digital measurement of the
remaining oil alkaline reserve (BN) within minutes.
Its embedded memory capability allows for fast
and simple monitoring of the BN depletion rate
over time
Test Principle
The test uses a reagent which produces a
pressure proportional to the alkaline reserve (BN)
of the oil. The pressure is measured by the digital
Rapid Oil Test Gauge and the corresponding
alkaline reserve (BN value) is displayed.
The method shows excellent repeatability and
correlation with ASTM D2896:
SAMPLE | BN (mg KOH/g) | ROTG Std Deviation | |||
ASTMD2696 | R0TGS1 | ROTG S2 | ROTG S3 | ||
1 | 105,0 | 101,2 | 101,7 | 102,0 | 0,40 |
2 | 69,8 | 63,3 | 63,2 | 63,4 | 0,09 |
3 | 57,2 | 55,3 | 55,3 | 56,7 | 0,73 |
4 | 40,0 | 42,2 | 43,2 | 43,4 | 0,64 |
5 | 29,6 | 29,7 | 29,3 | 30,2 | 0,23 |
6 | 15,1 | 13,0 | 13,2 | 13,2 | 0,13 |
