OLT testers are used for testing dielectric liquids with their breakdown voltage measuring. A-series of OLT testers works automatically, according with selected standard, which are preloaded. Designed in accordance with IEC 61010 safety requirements. Meets light industrial IEC 61326-1 Class B, CISPR 16-1, CISPR 16-2 and CISPR 22. 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
