Overview
The SD-SRT320 is a split-type surface roughness tester with a built-in thermal printer: measurement results and profile graphics are printed directly from the instrument, which is what production lines and incoming-inspection desks usually need. The external drive unit allows measurement in side, upward and other orientations that a one-piece instrument cannot reach.
With a 640 µm vertical range it covers coarse as well as fine surfaces. The 3.5-inch colour graphic LCD is a touch screen operated either by keys or by touch, and shows all parameters and graphics. A 7.4 V lithium-ion battery gives more than 50 hours of continuous working time, and 100 groups of original data and waveforms are stored internally with a real-time clock.
