The invention provides a modular measurement device 100 having, attachable to the quill 12 of a CMM, any one of a plurality of stylus support modules 120ab, 120cd, or 120ef. Attachable to a stylus support module is a range of stylus modules 110a-f. The stylus support modules have different spring rates to ensure that a near optimum response can be obtained for each stylus module used. The stylus modules may be configured so that each cannot be mistakenly fitted to the wrong stylus support module. The modules are held together by magnetic attraction, and the strength of attraction is cascaded so that the stylus module is removed first if pulled off.
