Hard Metal Magnetometer

DX-9700HC Magnetometer independently developed by Dexinmag company is the latest technology for measuring the magnetic properties of cemented carbides (WC in Co matrix) and semi-hard magnetic materials. 
 

The DX-9700HC magnetometer provides accurate magnetic parameters to evaluate other correlated properties; for example hardness or the presence of undesired phases. This revolutionary measuring equipment utilizes a technique that provides the fastest, repeatable and accurate measurements available on the market today. 
 

The DX-9700HC magnetometer meets the International Standards IEC 60404-4 and ASTM A596.

Functions:

◆ Supports Win XP/7/8/10 Chinese or English operating system, and supports Chinese or English display;
◆ The test waveform curve is displayed in real time during the measurement process, and the measurement can be stopped at any time;
◆ Automatic saving of measurement results (save by test number or manually intervene)
◆ Sample number, size, parameters and other data can be saved automatically to reduce manual errors;
◆ The software has a print preview function and can also directly print the measurement results and test curves;
◆ The measurement results and test curves can be output in BMP and other image formats and can also be exported in the form of data tables;
◆ At most, 4 measuring result curves can be superimposed and displayed at the same time, which can more intuitively compare the differences under different conditions;
◆ Built-in temperature coefficient of various materials can provide data reference for temperature correction;
◆ The measuring period is 30-120 seconds (depending on the type of sample and the proficiency of the operator).
