KF875, KF-UNI and KF-Lab Karl Fischer Moisture In Oil Test Sets

Over 20 years experience has led to the development of the Megger KF875, KF-UNI and KF-LAB Coulometric Karl Fischer Test Sets designed to determine moisture in oil, to provide highly accurate results on-site. The KF875 and KF-UNI are highly portable instruments, complete with integral printer and carrying case, are easy to use and provide highly accurate results. The KF-LAB unit is designed specifically for lab use is mains powered only and does not include a built-in battery or carrying case.

Optimized for testing insulating oils with a specific gravity of 0.875, the Megger KF875 simply requires the operator to press one button and inject a 1ml sample into the test cell. The 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.

The KF-LAB analyzes materials with an SG between 0.6 and 1.4, but also has a default setting optimized for analyzing insulating oils with an SG of 0.875. This means it can be used to measure water content in a variety of different materials but is also easy to set up for transformer insulating oils.
