MINISPIN是一種低成本高靈敏度的便攜式的低速磁通門式磁力儀。采用防震設計，電源或電池供電，所以它即可用于實驗室，也可以用于野外。就噪聲水平和方便性而言，它優于常規的實驗室用同類設備。樣品在三層屏蔽的鼓狀磁通門內繞垂直軸以6赫茲旋轉，信號輸出測量可以累積6秒或24秒。結果以兩個正交磁化強度分量在一塊6位的液晶面板上顯示。累積以數字化實現，信號的幅值和相位從傅立葉分析中導出。?
其最新的大樣品旋轉巖石磁力儀型號可能是目前世界上能夠實現測量50毫米方形樣品剩磁強度的唯一設備了。
?Minispin - Portable Rock Magnetometer is a low-cost, high sensitivity portable slow-speed fluxgate magnetometer. It is of rugged construction, battery or mains-powered, and it may, therefore, be used either in the field or in the laboratory. Its performance in terms of noise level and convenience is better than the conventional laboratory instrument. Specimens are spun at 6Hz about a vertical axis inside a triple-shielded, anulus-shaped fluxgate, the output from which may be integrated over 6 or 24 seconds. The results are displayed as two orthogonal components of magnetisation on a 5-digit liquid crystal panel. Integration is effected digitally and the magnitude and phases of the signal are extracted by Fourier analysis.
