SR300 Surface Roughness Tester

SR300 Roughness Waviness Tester - Lanetech's precision instrument for surface structure analysis of machined components. This versatile tester is ideal for workshop verification, laboratory analysis, metrology room applications, and on-site measurements.

 Measures five surface parameters: Roughness Profile, Waviness Profile, Primary Profile, Abbott Curve, and Motif Analysis;

Supports international standards: GB (China), JIS (Japan), ANSI (USA), DIN (Germany), and ISO;

Intuitive user interface for effortless operation;

Wireless WiFi connectivity for remote control capabilities;

Smart software saves configurations for different measurement scenarios;

One-click measurement for various workpiece types;

The SR300 eliminates complex adjustments through its pre-set configuration system, allowing operators to select settings and perform measurements with single button operation.

For optimal performance, please refer to the complete operating instructions.
