ULTRADEX®型是非常高精度的回转分度台,主要用计量检测校准、位置分度和其他实验台架上。360°、720°、1440°位置度是标准型号。对于一些特殊应用，几乎任何分度值都适用。
ULTRADEX MK IV 为重载回转分度台。它无论是在承载力和锁紧力方面都比MK II 型要大。它设计用来精密加工、检测、校准、测试齿轮和其他一些要求回转位置绝对精度1/2角秒。无累计公差正负1/8角秒且重复定位精度正负1/20角秒或者要求更好的应用。
这种型号回转分度转台利用一套非常高精度的端齿盘来位置分度。同时一旦位置锁定，它又能提供非常高的刚性，犹如一整体的钢柱。驱动方式可手动或自动，而且在增选附件后分度台可由水平状（垂直旋转轴）向另三个方向翻转90度，变成垂直状（水平旋转轴）这时从承载能力上可分为标准承载型、中等载荷型和重载型三种。每种都可提供从180度到1440度大范围的位置分度。"T"槽式螺孔的台面可供选择。
