A few days ago, our company invited the State Key Laboratory of Magnetism, Institute of Physics, Chinese Academy of Sciences, for our 3100 series of vibration sample magnetometers for the identification test, after a number of professors, experts composed of senior workers test, in the recent announcement of the results of the test.
3100 Series VSM Systems
After the expert group's test our new 3100 series VSM sensitivity can reach 65 nemu (10s/pt), the accuracy of magnetic moment is 1%, the maximum magnetic field is 3.2T, all of them reach the level of the same type of international famous brand VSM, and have such practical functions as unlimited angle of continuous rotation of the sample, automatically find the center and so on.
The test of this expert group is divided into three test items: maximum magnetic field, sensitivity and accuracy.
1: Maximum magnetic field test
The highest magnetic field test adopts NdFeB film samples, the test temperature is 23±1℃, the test conditions are 32kOe back to the line, the final results are as follows:
2: Sensitivity tests
The sensitivity tests were performed on empty sample rods in zero field, 5kOe, 10kOe and 20kOe environments, and on 10nm thick Co3Pd7 film samples in ±1kOe magnetic field environments, with a uniform test temperature of 23±1℃, and the test results are as follows:
3: Accuracy Tests
Accuracy tests were conducted for magnetic moment accuracy and slope accuracy respectively, the system was calibrated using NIST 772a and then measured Lakeshore standard nickel sphere samples, the test magnetic fields were 5kOe and ±5kOe respectively, the test temperatures were both 23±1°C, and the results of the slope tests were as follows, the
3100 series VSM is a new generation of VSM after nearly 10 years of independent research and development, the core components are localized devices, a variety of key indicators can be comparable to international brands of the same type of products, and has a high cost-effective, high-quality technology and service team and other advantages, you are welcome to call us for more information.
