Megger OTS60PB Oil Tester

The Megger OTS60PB automatic portable oil test set will perform accurate breakdown voltage tests on mineral, ester and silicon insulating liquids, providing repeatable results in the field. The test set comes with a lockable electrode gap adjustment ability, offering greater precision. One of the fundamental tests of oil quality is the breakdown voltage test, which is a measure of the oil's ability to withstand electric stress.

A low breakdown voltage can indicate the presence of contaminants such as water or conducting particles. The test voltage of the OTS60PB is electronically controlled to the maximum of 60kV and it has been designed to perform breakdown detection in terms of both voltage and current, which helps the range to comply with any future changes or developments in oil test standards. A unique feature of the Megger OTS60PB is that it provides custom test sequences, with the enhanced ability to download new standards from the Megger website and load them onto the instrument using a USB stick. Test results are identified either by a serial number or asset ID and are time and date stamped. An optional internal printer provides a hard copy of results. The three USB interfaces support PC connection, USB flash drive, external USB printer and barcode scanner.
