Description
Over 20 years experience has lead to the development of
the Megger KF875 and KF-UNI Coulometric Karl Fischer test
sets, instruments that are not only accurate and easy to
use, but are highly portable and suitable for On Site use.
Optimized for testing insulating oils with a specific
gravity of 0.875, the Megger KF875 simply requires the
operator to press one button and to inject a 1ml. sample
into the test cell. This simple 'one touch' operation makes
the KF875 so easy to use that it requires no specialist
knowledge or training to use it effectively.
Results are
presented on the instrument display and on the integral
printer in both micrograms of water and in milligrams per
kilogram (parts per million, ppm). The KF-UNI allows the
titration of samples with a range of specific gravities from
0.60 to 1.40 and also permits the
use of different sample sizes.
The printer may be
disabled if not required and results can be calculated in
ppm, mg/kg, % and micrograms. For extra flexibility, the
results may be calculated based on the weight of the sample
or based on the volume and specific gravity of the sample.
Truly Portable
Supplied as standard with a printer, low drift cell and
Ruggedized carry case the KF875 and the KF-UNI have been
specifically designed for outdoors use. Furthermore,
portability is enhanced by flexible power options - the
KF875 and KF-UNI can be powered from the mains supply, from
the internal rechargeable battery or via a 12 V car adapter.
Error
Compensation
Some Coulometric Karl Fischer sets are susceptible to
inaccuracies due to changes in the electrolysis cell
resistance, which requires the calibration of the reagent
being used.
The KF875 and
KF-UNI remove this need by using the patent pending ACE
Control System (Automatically Compensated Errors), which
guarantees that the electrolysis current produced and the
count rate displayed are always correctly synchronized,
regardless of changes to the electrolysis cell resistance
thus eliminating the need to calibrate the reagent further
adding to the instruments’ remarkable user friendliness and
ease of use. |
