Besides the insulation test, the insulation tester IL 3801F also includes a hipot and continuity test, thus making it a real all-rounder. It is ideal for simple, inexpensive and easy safety tests by national and international standards (IEC, EN, UL, VDE etc.)

Modern – convenient – flexible

The IL 3801F provides maximum comfort and ease of use through the 5.7'' TFT colour display built-in by default. Thanks to the personalised test programs, a fully automatic test plan can also be created. The DUT must therefore be connected only once – time-consuming replugging is a matter of the past!

Always flexible and ready for use at anytime

The IL 3801F features a fully electronic generator, which provides more accurate and faster testing. Due to 4-wire measurement technology, there is a separate repeat measurement of the test voltage, which ensures that the DUT is contacted properly. Thanks to the numerous interfaces, you will be spoiled for choice in terms of the control: be it via USB, Ethernet / LAN, RS 232 or 24V interface – the IL 3801F adapts to you and not vice versa!

All of these and much more!

With the help of our comfortable PC software, the IL 3801F can not only be controlled remotely, but it can also be extended by additional features and test steps.

With its compact housing, the portable IL 3801F is ideal as a portable desktop device. Thanks to the safety current limitation according to EN 50191, no additional protective measures (such as a test cover or two-handed operation) are necessary for the operation.
