The Starrett SR200 is a full featured, powerful and versatile surface roughness tester.  It 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.
The SR200 is truly portable with no PC or printer cables in the way of measurements - take it to
wherever you need to take measurements, save up to 100 batch readings and then download
to your PC or printer at your convenience.
