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.
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.
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.
