The new SR200 Surface Roughness Tester from The L.S. Starrett Co. is a powerful, full featured instrument that can be used either freestanding (on horizontal, vertical or even inverted surfaces) or bench-mounted with fixturing for batch measurement and laboratory applications. It is battery powered for portability, with an AC adapter available.

Fast and flexible, the SR200 can calculate ten parameters, covering a comprehensive range of roughness testing requirements. Its electronics provide very fast analysis, with results calculated and displayed even before the traverse unit returns. This rapid processing, combined with intuitive menu buttons, ensures measurement cycle productivity. The SR200 has a uniquely engineered stylus lift mechanism which allows a vertical adjustment of 2" (50mm) and rotation of the pickup to different measuring positions, including right angle or inverted measurements. These adjustments to the height and position of the gage allow areas and features of a part to be easily measured without additional complex fixturing, saving time. This feature saves the operator a huge amount of set up time and allows total flexibility. Typical applications where the stylus lift is invaluable include the measurement of steps, bores, grooves and lands.

The tester's large LCD displays a full menu and all measurement results. The user scrolls through the menus with the two control buttons, makes a selection and then presses the MEASURE key. All selections are saved for future measurements with a built-in memory capacity that holds up to 100 readings. The SR200 includes an RS232 port, so all measurement criteria and results can be readily exported. The SR200 includes TalyProfile Lite Windows software with powerful analysis features and on-screen graphic profile images. The software allows graphs, profiles and results to be arranged and printed within TalyProfile or exported to presentation software. TalyProfile Lite provides an easy upgrade path to the fuller featured Silver and Gold versions suitable for more advanced shopfloor inspection and laboratory analysis applications.

Out of the box, the SR200 package includes everything needed for a broad range of applications, eliminating the need for extra-cost options required with other products. In addition, an extensive range of pickups and accessories are also available to suit various measurement requirements.
