Surftest SJ-500 / 500P

The SJ-500 surface roughness tester provides the flexibility to be used either on a benchtop or in a portable manner, allowing for versatile operation according to user needs. It delivers highly precise measurement results, ensuring accuracy in surface roughness analysis.

Product Features 

The SJ-500 is the portable version of the desktop SV-2100 surface roughness tester, offering the same functionality in a portable form factor.

The SJ-500P model comes equipped with a desktop PC system, providing extended capabilities for data analysis and storage.

It supports measurements in the axial direction by swiveling the detector through 90°, making it possible to analyze shrouded features such as crankshafts.

The vertical adjustment knob allows for precise positioning of the stylus close to the workpiece, enabling measurements inside small holes and confined spaces.

The Digital Adjustment Tilting (DAT) function facilitates leveling of workpieces with an accuracy of ±1.5°, streamlining the measurement process.

The instrument features a highly visible 7.5-inch TFT LCD color display and a touch-operated panel, ensuring user-friendly and easy operation.

The simple input function allows for inputs based on drawing instruction symbols of ISO/JIS roughness standards, simplifying the configuration of surface roughness measuring conditions.

An optional manual column stand (178-085, 178-089) is available for the SJ-500, providing stability and convenience during measurements.
