SJ-410 – Portable Surface Roughness Tester

The Surftest SJ-410 is a portable surface roughness measuring instrument that is designed to deliver precise and smooth operation. It incorporates a range of innovative features to ensure accurate measurements. With its high straightness specification of 0.3 - 0.5μm over a traverse length of 25 - 50mm, it provides reliable and consistent results. The Surftest SJ-410 is also user-friendly and easy to use, making it an ideal choice for various applications.

Product Features 

It is equipped with a built-in 5.7-inch color graphic LCD touch-panel display, which is back-lit, ensuring superior readability, ease-of-use, and visibility even in dark environments.

The user interface and auto calibration function are designed to provide intuitive and user-friendly operation, simplifying the measurement process.

The digital filter function ensures non-distorted roughness profiles, leading to more accurate results.

An optional column stand (178-039) is available to enhance operability and provide stability during measurements.
The instrument includes a limited contour analysis function that supports four types of measurements: step, level change, area, and coordinate difference, enabling comprehensive analysis.

Password protection is available to prevent unintended operations and safeguard instrument settings from unauthorized access.

Measured data can be easily output to a PC using optional RS-232C or USB cable, allowing for further analysis and documentation.
