Rpk Surface Roughness Gauge

Rpk Surface Roughness Gauge

Surface Roughness Gauge Measuring Range Ra: 0.005~16.000μm Rz: 0.02~160.00μm Data Storage 100 groups Relative Humidity <90% Working Temperature -20°C~40°C

Rpk Surface Roughness Gauge is suitable for production site, it can measure Rpk, Ra, Rz... 20 roughness parameters. measures variety of surface roughness of machined parts, according to the measurement conditions and the corresponding parameters of selected, shows clearly the measurement results and graphics in liquid crystal screen , and can output on a printer, can also communication with PC.It is especially suitable for field inspection of large workpieces and production lines, as well as outside verification of inspection, measurement and commodity inspection departments.

1. The roughness measuring head uses high precision inductance sensor, and the measurement value is stable and accurate

2. The curved surface sensor can be selected to measure the roughness of concave and convex surfaces, and the inner hole roughness can be measured by the small hole sensor.
