The Megger KF875 (6111-636) Portable Karl-Fischer Oil Test Set is a portable, precise and practical unit capable of determining the moisture content of insulating oil with a specific gravity of 0.875. It utilises the Karl Fischer coulometric titrimetry method in order to determine moisture content. This method is the industry standard, thereby ensuring that the Megger KF875 (6111-636) Portable Karl-Fischer Oil Test Set is compliant with ASTM D1533, BS EN 60814:1998 and IEC 60814:1997 regulations.

The Megger KF875 (6111-636) Portable Karl-Fischer Oil Test Set is comprised of a test unit, printer, low drift cell and rugged carry case. The printer can be disabled if the user does not require a physical copy of the results.

Results are also indicated on the display in parts per million (ppm) and milligrams per kilogram (mg/kg); they can be calculated from the weight or the volume and specific gravity of the sample, allowing the user to tailor the Megger KF875 (6111-636) Portable Karl-Fischer Oil Test Set to the application and/or his/her preferences.

Working to improve the accuracy of the Megger KF875 (6111-636) Portable Karl-Fischer Oil Test Set is its Automatically Compensated Errors (ACE) Control System. This patent-pending feature prevents inaccuracies caused by changes to the electrolysis cell resistance by ensuring that the electrolysis current and the count rate are always synchronised correctly. This also eliminates the need for frequent checks of the titrator's efficiency, improving the practicality and ease-of-use of this test set.

Also adding to the practicality and ease-of-use of the Megger KF875 (6111-636) Portable Karl-Fischer Oil Test Set is its simple operating system. The user needs only press a single button and add 1ml of the sample to the cell in order to commence testing.

Moreover, as the Megger KF875 (6111-636) Portable Karl-Fischer Oil Test Set can be powered using a mains supply or rechargeable batteries, the user is able to standardise testing by using the same equipment whether in the field or in the laboratory. Additionally, battery operation facilitates in-the-field testing preventing the deterioration of the oil samples.

Flexible power options improve the Megger KF875 (6111-636) Portable Karl-Fischer Oil Test Set’s portability and practicality which, when combined with its precision, makes it a reliable, adaptable and easy-to-use Karl Fischer coulometric titrimetry kit.
