The Roughness tester is a portable, battery-powered instrument for checking
surface roughness with the measured values displayed on a digital readout. This
instrument can be used in the laboratory, inspection area, shop, or wherever on-
site surface roughness testing is required.
1. Description
NOTE: Even though this instrument is designed and built to with-
stand the rigors of handling and use, it is a precision instrument and
should be treated with care to assure measurement accuracy and
reliable performance.
All Roughness Testers include:
Model 14-415-4
Model 14-416-2
