2018 New Design Surface Roughness Tester
Jul 17, 2018

2018 new design surface roughness tester


 

Portable Surface Roughness Tester KR310 

is a high accuracy instrument for measuring surface roughness. It can be used on variety of machining parts and operates on various surfaces, not only flat but also outer cone, outer cylinder, curved, pinholes, grooves, recesses grooves and axle etc.

 

Application

Portable Surface Roughness Tester KR310 allows surface roughness measurement both on metal and non-metal workpieces. It is suitable for machining and manufacturing, quality control, inspection departments, especially for measurement on large and heavy workpiece, assembly line on site. The KR310 is a Non Destructive Testing instrument, damage won’t caused to testing piece.

 

Main Feature

Mechatronics and ergonomics design, small size, light weight, easy to operation  

Drive unit can be either stored inside main unit or split from it, which enables freely adjustable test in each direction, such as up, side, etc.

DSP chip control and data processing, high speed, low power consumption

22 Parameters: Ra ,Rz, Rq, Rt, Rp ,Rv, R3z, R3y, Rz(JIS), Rs, Rsk, Rsm, Rku, Rmr, Ry(JIS), Rmax,RPc, Rk, Rpk, Rvk, Mr1, Mr2

Measurement range up to 160μm (can be optional to 320μm)

3.5 inches color graphic LCD touch screen, wide viewing angle, excellent readability and an intuitive rich display, it includes a backlight to improve visibility in dark environments

Can be operated using buttons or touch screen
