Separate Surface Roughness Tester Profilometer (Ra, Rq, Rz, Rt)

This small, lightweight, and easy-to-use surface tester measures multiple parameters such as Ra, Rz, Rq, and Rt. It features four wave filtering methods: RC, PC-RC, GAUSS, and D-P. For enhanced functionality, you can connect the tester to a computer for statistics, printing, and analysis by adding the optional USB cable and CD software interface to your purchase.

Application: Widely used in production sites to measure the surface roughness of various machinery-processed parts and calculate corresponding parameters based on selected measuring conditions.
