Introduction :

VEER make Digital Epstein Tester VET-1608 is complete stand alone Instrument to measure AC magnetic properties of Electrical Steel of all grade and gauges mostly. It refers ASTM-343, IEC 60404-2, IS:649 St Other Standards. Epstein Frame testing method is standard 8L worldwide accepted method to test important magnetic parameters like Watt/kg, VA/kg, Magnetizing Force, Permeability, Form Factor etc on different Induction (Flux Density). We provide Software to Generate Test Report in Excel file and Graphs. Hysteresis Curve (B/H) facility also available in VET-1608 on request.
