The new SJ-411/412 has numerous innovative features combined with high accuracy and a competitive price makes this instrument the new leader in its class.

Surftest Series 410

SJ-411/SJ-412

One of the most econimacal skidded or skidless,easy to use roughness testers.

Unit has the ability to take straightness and waviness measurements using the skidless measurement function.

A skidless detector and a curved surface compensation function provide efficient evaulation of cylinder surface roughness
