介绍了一种轻便、便携、廉价的u通道样品磁化率跟踪器。该轨道使用Sapphire Instruments 3.3 cm方形线圈，其形状响应函数类似于2G-Enterprises u通道磁力计的形状响应函数，半峰宽度为3 cm。该仪器已使用二氧化锰制成的u通道标准进行了校准。该软件集成了自动跟踪控制和测量漂移校正。该系统的磁化率测量结果与法国伊维特河畔吉夫科学研究所（Gif‐sur‐Yvette，France）用于u通道样品的45 mm圆形巴丁顿环以及大洋钻探计划研究船JOIDES Resolution上的整个岩心磁化率跟踪数据相比毫不逊色。
A lightweight, transportable, and inexpensive magnetic susceptibility track for u channel samples is described. The track utilizes a Sapphire Instruments 3.3 cm square coil having a response function of shape similar to that of the 2G‐Enterprises u channel magnetometer, and a half‐peak width of 3 cm. The instrument has been calibrated using a u channel standard made of manganese dioxide. The software incorporates automated track control and measurement drift correction. Susceptibility measurements on this system compare favorably with the 45 mm circular Bartington loop used for u channel samples at the Laboratoire des Sciences du Climat et de l'Environnement (Gif‐sur‐Yvette, France) and with data from the whole core susceptibility track aboard the Ocean Drilling Program research vessel JOIDES Resolution.
