● Compact and lightweight
● Precise voltage measurement
● Simple for operator
Test results are saved into non-volatile memory of oil tester. A PC-connectivity makes it easy to collect data from oil tester, save and store them as well as print a fulfilled report. Test voltage is being measured directly on electrodes. This fact combined with a true sine voltage shape (independent from supply voltage shape), increases repeatability and accuracy of measurements.
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. Test vessel for this series goes with magnetic stirrer, which stirs a liquid between two measurements.
Both A and M series of oil 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 oil 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.
A-series provides with fully automatic test procedure according to selected standard (basically IEC 60156 and GOST 6581 settings are preloaded). It has a built-in printer which is able to print a test report after procedure is done.
