Result Comparison
Symptom
Possible Cause
Possible explanation and Solutions
Results from DIGI+ are
different than those from
a laboratory test
Samples continue to age
after being taken
A sample with water and / or low BN can continue to age
such that the chemical composition of the oil is different to
when it was tested.
Differences within
repeatability limit
of DIGI+
All analytical methods, especially those requiring careful
measurement of samples and reagents, can vary between
tests. For maximum accuracy, a new pipette or syringe
should be used, taking care when adding reagents to the
sample cup.
DIGI+ uses different
measurement principles
than laboratory tests
DIGI+ uses chemicals to react with components in the
oil. Laboratory water tests such as Karl-Fischer or IR
methods such as FTIR or NDIR can give different
measurements and have their own non-repeat and
accuracy issues.
Laboratory methods also measure the total amount of
water present. DIGI+ reagent reacts readily with free and
emulsified water however dissolved water, and any held
by the oil additive package, may not be accessed by the
reagent. Laboratory methods such as IR do not
discriminate what form the water is within the oil.
