SJ-220
A portable surface roughness tester designed like a hand tool for easy on-site use
The SJ-200 series of portable surface roughness measuring instruments that has contributed to industrial development and technological progress through precision measurements, has evolved further still.
While maintaining excellent portability and ease of use on-site, it also provides touch screen functionality for intuitive operability.
Equipped with a built-in battery, it can perform measurements in environments where power is not available and can be used approximately 1000 times on a full charge.
Cableless and paperless work is made possible by using the U-WAVE-TIB, a Mitutoyo wireless data transmitter.
This is a user-friendly device that provides compatibility and versatility to meet diverse manufacturing needs.
