Surftest SJ-301

A portable surface roughness tester with a touch-panel LCD and a built-in printer

Conforms to the JIS (1994-1998), ISO, DIN, and ANSI standards.

Graphic display of measured profile
Easy-to-operate touch-panel
Built-in printer and battery operation
JIS/DIN/ISO/ANSI compatible 25 evaluation parameters and 3 analysis graphs
300μm wide measuring range detector
Statistical processing function included
Compatible with PC based Surfpak-SJ software
Dual power supply (AC adapter/Rechargeable battery)
Auto-sleep function for power conversion

Conforming to various standards

Conforming to the JIS (1994-1998), ISO, DIN, and ANSI standards.
Additionally, the horizontal roughness parameters S, Sm, tp (mr) can be reported. The SJ-301 also performs such special parameters as plateau rate and RK-related parameters.

Storing measurement conditions and data

The SJ-301 main unit can store a maximum of 5 sets of measuring conditions. Individual measuring conditions can be selected for each workpiece.
The measuring conditions stored in the SJ-301 can be recalled and switched by direct key operations.
Measured data can be saved at the measurement site & be printed out or recalculated later.
By using an optional memory card, a maximum of 20 sets of measuring conditions, measured data, and statistical results can be stored.

Key-masking function

This function limits touch panel operation to prevent the detector calibration data and measuring conditions from being altered or deleted.
Measuring conditions can be easily controlled among multiple users. Resistance to environment
The SJ-301 keypads have excellent durability — No need to worry about oil stains from the user’s hands.

Reading profiles in the LCD window

Measurement results and analysis profiles can be read in the LCD window.
Signal waves can be scrolled smaller or larger, enabling the operator to read fine details.

High-speed thermal printer

Equipped with a highly sophisticated, high-speed thermal printer.
Selectable orientation for printout — Choose the portrait for conventional printout or the landscape for printing out the image as it is displayed.
BAC (Bearing Area Curved ADC (Amplitude Distribution Curve) can be printed out.

Statistical analysis functions

Statistical analysis of one parameter is possible.
Displays and prints frequency histograms as well as statistical calculation results (average, standard deviation, maximum value, minimum value, pass ratio).

Auto calibration

Calibration can be easily performed by simply inputting and measuring the Ra value inscribed on the roughness reference specimen.
No adjustment with a tool, such as a volume adjustment, etc. is required. GO/NG judgment function
Tolerance values in three-steps can be set for the surface roughness parameters
Judgment symbol is displayed in the result display for a quick judgment of GO/NG.

Customization function

The user can select only the parameters needed from a variety of surface roughness parameters provided.

Mobility

A built-in battery in the SJ-301 makes it possible to inspect surface roughness even at a site where there is no electrical outlet available.
Portable and convenient — the drive unit and the detector can be stored in the display unit. (Carrying case is a standard accessory.)
Measurement can be performed while the display unit is in the carrying case. The carrying case can be used to protect the display unit.

Arbitrary evaluation length

An arbitrary evaluation length within the range of 0.3 mm - 12.5 mm (Unit: 0.1 mm)
can be set.
Measurement in a limited space, where measurement is difficult under the measuring conditions in accordance with JIS standards, is made possible by using the start-up OFF function.

One-step detector replacement

Special detectors are available for measurements that cannot be performed with a standard detector - such as measurement of small-diameters and deep-grooves.
No tool is required for replacing the detector. Simply pull out and insert a detector.
Just one SJ-301 can perform measurement on a variety of workpiece's, since various types of detectors, depending on the workpiece, can be used.

High-accuracy detector

SJ-301 employs a differential inductance method, which is used in high-end models.
Measurement with a high-accuracy and a wide measuring range of 300μm.
Parameters that require high-accuracy feed such as SM and S can be measured with the SJ-301.
The detector can be retracted into the drive unit when the SJ-301 is not performing a measurement.

Selectable language for display/ printout

Display/ printout language is selectable from among English, German, French, Italian and Japanese.
