Surface measurement testersAMETEK Taylor Hobson says it has added two new products to its range of surface measurement testers. These are the Surtronic Duo portable surface roughness tester for shopfloor and on-site measurement of multiple roughness parameters and the Intra Touch contour and finish measurement system for applications including precision machining.

The company says the Surtronic Duo uses a long-wearing diamond stylus that is drawn across a part with a precision motorised traverse mechanism. Vertical movement of the stylus is detected by a piezo-electric pickup that converts mechanical movement into electrical signals.

Intra Touch provides all surface finish capabilities claims the company, including fundamental roughness and waviness parameters, contour and form error analysis, feature exclusion and zoom tool.
