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

• Certied specimen (nominal)

• 9 volt alkaline battery

• Screwdriver

Model 54-410-500-0, (54-410-511-0 with RS-232) are furnished with a certied

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 certied

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.
