DX-2012H DC Hysteresis Graph Test System
Hard Magnetic Materials Measurement
BH loop tracer for measuring remanence, coercive force and maximum magnetic energy product of permanent magnetic materials including ferrite, AlNiCo, NdFeB and samarium cobalt.
Product Overview
DX-2012H DC Hysteresis Graph Test System is a BH loop tracer designed to measure the magnetic properties of permanent magnetic materials. The system measures important magnetic parameters including remanence (Br), coercive force (Hcb), intrinsic coercive force (Hcj) and maximum magnetic energy product (BHmax).
It is suitable for testing various permanent magnetic materials such as ferrite, Alnico, NdFeB and samarium cobalt. The system can automatically generate BH hysteresis loops and demagnetization curves for accurate analysis of magnetic performance.
The DX-2012H system conforms to China National Standards GB/T 3217-92, GB 11209-89, and international standard IEC 404-5.
Key Features
- Automatic measurement of saturation hysteresis loops
- Measurement of important magnetic parameters including Br, Hcb, Hcj and BHmax
- Automatic demagnetization curve measurement for rare-earth permanent magnets
- Suitable for ferrite, rubber magnets, AlNiCo, NdFeB and SmCo materials
- Supports multiple sample shapes including ring, square, tile and irregular samples
- Computer-controlled testing and data processing system
- Optional high-temperature measurement up to 220°C
Measurement Capabilities
The system automatically measures magnetic parameters such as:
- Saturation magnetization (Js)
- Remanence (Br)
- Coercive force (HcB)
- Intrinsic coercive force (HcJ)
- Maximum magnetic energy product (BHmax)
- Recoil permeability (µrec)
Rare-earth permanent magnet materials can be measured in the second quadrant to obtain parameters such as Br, HcB, HcJ, Hk(H90) and BHmax.
