SRT-9000S 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.

Composite structure of main display unit ,driver unit and Sensor. Electromechanical integration design, small size, light weight, easy to operation

The stylus drive unit can be stored within the main unit for normal measurement, or separated driver from the display unit by using the supplied cable which allows more flexible measurement in any orientation.

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

It can measure side walls, upwards and other directions, can be equipped with accessories such as height gauge and measuring stands to perform various posture adjustment and positioning measurements of complex workpiece.
