Digital Epstein Tester

We are offering digital epstein tester. Ep-350 is designed to achieve hassle free operation in single unit, for measurement of ac magnetic properties of flat rolled magnetic materials at high frequency by using watt meter, ammeter, voltmeter and source. This test method is a fundamental method for evaluating the magnetic performance of flat-rolled magnetic materials in either as sheared or stress relief annealed condition. This test method is suitable for design, specification acceptance, service evaluation, and research and development.
Ep-350 has digital controlled crystal accurate 16 bit sine wave generator, which provides 25 hz to 450 hz harmonics free non distorted power for testing of specimen. It has built in required (digital sampling) measuring meter, as flux voltmeter, rms voltmeter, rms ammeter, peak ammeter, wattmeter and power factor meter. These measuring devices are (temper proof) precisely calibrated to achieve high accuracy and long term stability. Accuracy and stability of ep-350 is better than specified in national and international standards.
User friendly operation and multiple use of ep-350, make its world’s leader of magnetic measurement. It has two operation mode one is standard 25 cm epstein mode and another is user mode. User can test 30 mm wide and 305 mm long strips specimen in 25 cm epstein mode. Convention method consist of individual mounting of source and measure so they does not link each other hence a qualified engineer is required to handle these devices, that for most of technical people think that epstein tester is too much complicated method to test electrical steel sheet. Ep-350 has been removed those types of complications, so only details of specimen like weight, length, density, frequency, % ofeddy current and induction has to be enter by simply using instrument keys. After proper feedings of required data, only press a start key and instrument directly shows on lcd display, watt per kg, watt per pound, atm, magnetizing force and permeability.
