Thông tin sản phẩm

Both A and M series of OLT testers bring out accurate and repeatable results of measured breakdown voltage. Fast high-voltage switch off time makes it possible to carry out test of dielectric liquids, which are easily destroyed under such influences.

The internal design of OLT testers combined with a use of automatic high voltage breakers, cutting off supplied voltage if tester’s lid has been opened during the test, provide operator with high level of safety.

Testers are fully equipped and are ready for operation right after unpacking. They come with a test vessel (IEC 60156 – basic configuration) with VDE 0370 mushroom-shape electrodes. A gap between electrodes is easily regulated with a use of pass-no pass gauge, which comes in pack.

M-series provides operator with ultra-simplicity of operation. It doesn’t require any presets. All you need is pressing start button after a test vessel is loaded. Tester will show a breakdown voltage result immediately after breakdown occurs.


MAIN FEATURES:
