An upgraded version of Megger's OTS60AF laboratory oil tester, the OTS80AF is capable of accurately determining the breakdown voltage level of insulating oil by applying test voltages of up to 80kV.

The tester is suitable for use on mineral, ester and silicon insulating liquids and features a lock-in precision oil vessel with lockable adjustment to hold the sample safely within the testing chamber. Once this is inserted and the lid is shut the tester will gradually apply voltage levels to the oil sample until breakdown of the insulating liquid takes place. Information about this process is relayed through a full-colour LCD screen that is built into the front of the tester and it is also possible to directly view the sample breakdown taking place by looking through a transparent lid on the top of the device. Once inserted into the chamber and locked down the oil sample is safe and if any problems occur the system can be shut off instantly to safely disperse high voltage levels.

As standard the OTS80AF comes with a selection of universal oil testing sequences and also allows the user to configure up to three test sequences depending on preference and need. The oil vessel included as standard with the tester is 400ml, but it is also possible to purchase a 150ml optional vessel as well for the use of smaller samples.

To make sure you've got extensive documentation about oil testing the OTS80AF is compatible with PCs and printers to manage asset information and to print off testing records.
