The Mitutoyo Surftest SJ-210 (178-561-02A) is a portable,
handheld surface roughness tester with a 2.4-inch, color,
backlit, LCD touch screen that displays in vertical or horizontal
orientations, and left- and right-hand data views in 16
languages, measures 39 parameters, and has a micro-SD card that
stores up to 10,000 results. A surf tester, also known as a
profilometer, surface roughness tester, roughness gage, or
surface finish gage, is a device used in metrology to inspect and
measure surface roughness in shop, metalworking, manufacturing
and quality control (QC) applications.
This surface tester has an Ingress-Protection (IP)-53 rating for
water and dust resistance. It displays total and sectional
measurement results, assessed profiles, evaluation curve, bearing
area curve (BAC), amplitude distribution curve (ADC), and
waveform results. Profile images can be zoomed up or down. The
Surftest can display results in sixteen languages. An integrated
micro-SD card stores 10,000 measurement results, and supports
screen capture. A built-in battery allows for approximately 1,000
measurements with four hours of charging time. The unit’s memory
stores up to 10 measurement conditions, and one measured profile.
Operational keys on the front of the unit and under the sliding
cover are labeled, and display settings have left and right arrow
keys. Keys are displayed on the front of the unit, and
additional, less frequently used keys are hidden under the
sliding cover to prevent unintended operations. The unit has a
stylus alarm that indicates when cumulative measurement distance
exceeds the preset limit. The detachable drive unit can be
separated from the display unit with a cable for maneuverability.
The SJ-210 has auto-calibration that can be initiated with
numerical value entry, and gain adjustment for color clarity. An
auto- function can be activated to automatically turn the
power off, if there has been no operation for 10 to 600 seconds.
Measurement conditions are saved when power is turned off. The
unit has parameter customization for calculation and display. It
has a “go/no-go” (G/NG) parameter judgment with maximum value of
16% rule option, and ANSI standard deviation selection option.
The Surftest SJ-210 (178-561-02A) is pas-protected to
protect settings and to prevent unintended operations. It has a
USB 2.0 interface with digimatic Statistical Process Control
(SPC) cable for data collection, RS-232C output, and can be
connected to a printer and a footswitch. A memory card slot
supports data storage. It works with Microsoft Windows 2000 SP4,
Windows XP, Windows Vista, and Windows 7 operating systems, and
Microsoft Excel 2000, Excel 2002, and Microsoft Office Excel
2007. The unit includes a roughness specimen, and comes with a
carrying case that has a belt loop attachment.

A surface roughness tester, also known as a profilometer,
surtest, roughness gage, surface finish gage, or surf roughness
tester, is a device used to inspect and measure surface roughness
of flats, rounds, sloping planes, and recesses in machined,
ground, or polished metal and non-metal surfaces. It is used for
metrology in shop, metalworking, manufacturing, and quality
control (QC) applications. Surface roughness testing is a type of
form measurement that identifies surface profiles such as grooves
and recessions, commonly known as peaks and valleys, of a
surface. A roughness tester traces a surface profile using a
skid-type (contact-type) method with a tracer tip such as a
diamond stylus and piezo-electric detection to calculate
roughness. Common types of parameters include Ra (roughness
average), Rv (maximum profile valley depth), and Rsk (skewness),
and assessed profiles. Profiles can have valuations such as
cutoff, sampling, traversing, and evaluation-types of lengths. A
surface roughness tester can have analog or digital display. A
surface roughness tester can be portable, handheld, or
desktop-type.
