25 mm (1 inch) diameter strain-gauge touch probe with autojoint mounting, suited to high accuracy part measurement.

TP7 with PI 7-3

The TP7M probe is an electronic probe using strain gauge technology, which gives higher accuracy, eliminates lobing and reseat errors and offers a much longer life than kinematic touch-trigger probes.

Incorporating a multi-wired autojoint connection, the TP7M is compatible with the PH10M PLUS / PH10MQ PLUS motorised heads, PH6M fixed probe head, plus the range of multi-wired extension bars (PEM).
