Portable Surface Roughness Tester

Surftest SJ-400 Series 

Revolutionary New Portable Surface Roughness Testers Make Their Debut 

Long-awaited performance and functionality are here: compact design, skidless and 

high-accuracy roughness measurements, multi-functionality and ease of operation. 

Requirement 

1 

High-accuracy measurements with 

a hand-held tester 

A wide range, high-resolution detector and an ultra-straight drive 

unit provide class-leading accuracy. 

Detector 

Measuring range: 800µm 

Resolution: 0.000125µm (on 8µm range) 

Drive unit 

Straightness/traverse length 

SJ-401: 0.3µm/.98"(25mm) 

SJ-402: 0.5µm/1.96"(50mm) 

SJ-402 


Requirement 

2 

Roughness parameters that conform to 

international standards 

The SJ-400 series can evaluate 36 kinds of roughness parameters 

conforming to the latest ISO, DIN, and ANSI standards, as well as to 

JIS standards (1994/1982). 

2 

Requirement 

3 

Cylinder surface roughness measurements with 

a hand-held tester 

The skidless measurement and R-surface compensation functions 

make it possible to evaluate cylinder surface roughness. 


Requirement 

4 

Measurement/evaluation 

of stepped features and straightness 

Ultra-fine steps, straightness and waviness are easily measured by 

switching to skidless measurement mode. The ruler function enables 

simpler surface feature evaluation on the LCD monitor.

Requirement 

5 

Advanced data processing with extended 

analysis 

The SJ-400 series allows data processing identical to that in the 

high-end class. These data analysis and report creation capabilities 

are achieved using the surface roughness analysis program 

SURFPAK-SJ. 

Requirement 

6 

Confirmation of measurement results and 

assessed profiles without a printout 

The large, integrated, touch-panel LCD monitor clearly displays 

evaluation results and measured profiles.

The SJ-400 Series 

Performs Skidless Measurements 

The SJ-400 series detector uses interchangeable nosepieces that allow skid- or skidless measurements to suit the type of 

measurement required.

Tilt compensation function 

• The Tilt Compensation Datum Points are selectable from 

all of the profile (choose P1 and P2) or any arbitrary 

two sections on the profile (choose P1, P2, P3 and 

P4), as required. If you choose adjacent sections for tilt 

compensation then the 

characteristics of 

features of interest 

between these sections, 

such as scratch depth, 

etc, can be measured 

directly.

Simplified surface feature evaluation 

with the ruler function 

• This function determines the coordinate difference between 

two arbitrary points so feature characteristics, such as step 

height and width, etc, can be measured.

Powerful Support for Leveling 

The height/tilt adjustment unit comes as standard for leveling the drive unit prior to making skidless measurements 

and, supported by guidance from the unique DAT function, makes it easy to achieve highly accurate alignment.

More Measuring Functions 

Than Expected From a Compact Tester 

Measuring curved-surface roughness 

(skidless measurement) 

Usually, a spherical or cylindrical surface (R-surface) cannot be 

evaluated, but, by removing the radius with a filter, R-surface data is 

processed as if taken from a flat surface. 

Measurement 

of a cylindrical 

surface 

R-Surface 

compensation 

Built-in thermal printer 

A high quality, high-speed thermal printer prints out measured 

results. It can also print a BAC curve or an ADC curve as well as 

calculated results and assessed profiles. These results and profiles are 

printed out in landscape format, just as they appear on the LCD, in 

easy-to-understand form. 

6 

Statistics 

Statistical processing can be performed on multiple measurements 

for one roughness parameter. Histograms can be displayed and 

printed in addition to statistical results (mean, standard deviation, 

maximum/minimum value and acceptance ratio). 

Statistical 

Switchable 

Histograms

GO/NG indication 

Upper and lower tolerance limits can be set for up to 3 roughness 

parameters. A GO/NG indication is displayed after a measurement. 

The calculation result is highlighted if NG. 

Calculation Result Screen with GO / NG judgment result 

Real sampling 

This function samples stylus displacement for a specified time 

without engaging detector traverse. This function has a wide range 

of uses, such as a simplified vibration meter or a displacement gage 

incorporated in another system. 

Recalculating 

Key masking 

GO sign 

NG sign 

Previously measured data can be recalculated for use in other 

evaluations by changing the current standard, assessed profile and 

roughness parameters. 

Arbitrary length measurement 

This function allows a sampling length to be arbitrarily set in .004" 

(0.1mm) increments SJ-401: .004" to .98" (0.1mm to 25mm), 

SJ-402: .004" to 1.96" (0.1mm to 50mm). It also allows the 

SJ-400 series to make both narrow and wide range measurements. 

Locks out input from the touch panel keys. This eliminates the 

possibility of the operator accidentally changing the calibration or 

measurement conditions.

Calibration Screen 

Auto-Calibration 

The SJ-400 series is equipped with Ra calibration and step 

calibration methods for detector calibration (gain adjustment). In 

both calibration methods only the calibrated value of the precision 

specimen needs to be entered. No other operations are required to 

calibrate the tester. 

Storing/recalling measured data and conditions 

The measurement conditions and data can be stored in the control 

unit or memory card (optional) and recalled as required. Batch 

printout of data after on-site measurement improves measuring 

efficiency. 

Storage capacity 

Measurement Control unit: 5 conditions 

conditions 

Memory card: 20 conditions 

Measurement data Memory card: 50 or more pieces of data 

Customizing 

The SJ-400 series can be set up to calculate and display only a 

subset of the roughness parameters available. Parameters can be 

added later for recalculation, if required. 

Customized Screen

Wide Choice of Evaluation Possibilities 

with Analyzing Program 

Surface roughness analyzing program SURFPAK-SJ 

The SURFPAK-SJ program gives the SJ-400 series the same excellent 

operability and advanced analysis performance achieved by highend 

desktop testers. More roughness parameters and analysis 

graphs are available, unnecessary data can be filtered out and 

surface features, including step and pitch, can easily be evaluated. 

SURFPAK-SJ transforms this small machine into the equivalent of a 

high-end desktop evaluation system.
