Our company has been engaged in magnetic hysteresis, coercivity, intrinsic coercivity, remanence, magnetic field and other magnetic properties automatic test apparatus development for 20 years. There are many excellent technology professors with profound theory, and strong sense of innovation in our company. Our magnetic hysteresis test products, DMT series hysteresigraph, whose hardware and software are unique in the field, receive lots of home customers' compliments and hold a rather great market control rate, they are ideal for both R&D and production line testing of magnetic materials. When entering into international market, they also win a good reputation. We lay great emphasis on the reliability of quantity and after-sale service, and win universal praise. We heartily appreciate the favor and recommendation of our customers to our products for years and sincerely expect you to become our new customer and new friend

DMT-4 automatic hysteresigraph system accords with the standard permanent magnet test system, GB3217-92, used to measure the major and minor hysteresis loops, demagnetization curves, recoil hysteresis loops and initial magnetization curves in different temperature of ferrite, AlNiCo, SmCo, NdFeB and quenched material, and gives the magnetic parameter, Br, Hcb, Hcj, (BH)max, Hk and so on, and could meet different requirements on test function, precision, power capability, reliability, efficiency, price, local environment from laboratory to enterprise's production line.
The quality of DMT-4 disposes is reliable. There are large-scale, medium-scale and small-scale,7 models in all, of electro-magnets to be chose. Welcome to enquire and ask for data!
