Repair of poor accuracy of Sanfeng roughness tester SJ-210, product calibration, product measurement, etc!

Since the launch of the SJ-210 series in 1999, Japan's Sanfeng multifunctional portable surface roughness tester has earned a reputation for ensuring high-precision driving units, straightness measurement, Skidless support, and the ability to measure laboratory environments beyond waves and complex shaped surfaces. The fiercely competitive surface measurement market today requires more and higher functionality measurements and analyses than before. To meet these demands, Sanfeng has withdrawn from the new SJ-210 series, which includes all the basic functions of a roughness tester and has better performance.

Repair of Sanfeng roughness tester SJ-210：

This series supports both track and trackless measurements. Equipped with 46 roughness parameters that comply with ISO, DIN, ANSI, and JIS standards.

A wide range, high-resolution detector and a driver provide higher precision measurements compared to similar products.

<Measurement Range/Resolution>

800 μ m/0.0125 μ m resolution (8 μ m measurement range)

<Straightness/Movement Length>

SJ-411 drive unit: 0.3 μ m/25mm

SJ-412 drive unit: 0.5 μ m/50mm

The trackless detector and arc-shaped surface compensation function enable it to effectively evaluate the surface roughness of cylindrical objects.

The ultra fine step difference, straightness, and waviness can be measured using the trackless measurement function.

U handheld portable data processing unit and 5.7-inch color graphic LCD touch panel provide outstanding readability and operability. LCD also has backlight function, which improves visibility in dark environments.

The measurement data can be output from an external PC through an RS-232C interface cable (optional).

U comes with a standard plate for correcting roughness.

The digital filtering function can obtain an undistorted surface roughness contour map.

U GO/NG judgment function.

Automatic calibration function.

The U display interface supports 16 languages and can be freely switched.

The simple contour analysis function supports four types of measurements: step, horizontal change, area, and coordinate difference.

Each function can be password protected to prevent accidental operations and protect your settings.

If the optional accessories can be installed on the bracket, it can significantly improve operability.
