1. Description
The Roughness Tester II 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 onsite surface roughness testing is required.
NOTE: Even though this instrument is designed and built to withstand 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:
•Roughness unit
•General purpose probe
•Certified specimen (nominal)
•9 volt alkaline battery
•Screwdriver
Model 54-410-500-0, (54-410-511-0 with RS-232) are furnished with a certified specimen and 0.0004" probe.
*Probe supplied with a 90° conical diamond stylus, 0.0004" (10µm) radius per
ANSI-B46, ISO and MIL specs.
Model 54-410-600-0, (54-410-622-0 with RS-232) are furnished with a certified specimen and 0.0002" probe.
*Probe supplied with a 90° conical diamond stylus, 0.0002" (5µm) radius per
DIN-4768 and certain ISO specs.

3. Measurement Parameters
Ra Roughness Average— the arithmetic average height of roughness irregularities measured from a mean line within the evaluation length(L).
MEAN LINE
Ra= 1/L ∫ | y | dx≈(y1+y2+y3+…+yn / n
Rz Maximum Roughness Depth— the largest of the peak-to-valley roughness depths in the evaluation length.
