Portable roughness tester for fast detection of Ra, Rz, Rq and Rt /
Large OLED display / Micro-USB interface / With calibration plate and roughness standard / Measuring software / Permanently installed li-ion battery
The roughness meter has a protective cap for the sensor, which protects it from external influences and can be easily screwed to the device. A calibration plate with roughness standard is also part of the standard equipment and serves to check the correctness of the measurement results.
Rz = average roughness
The average roughness Rz is the arithmetic mean of the largest single roughness depths of several adjacent individual measuring sections.
Ra = arithmetic centers roughness
Ra is the generally recognized and internationally applied roughness parameter. It is the arithmetic mean of the absolute values of the profile deviations within the reference line. The measured value Ra is always smaller than the Rz value determined on the same roughness profile.
Calibration certificates are issued specifically for the customer and are excluded from the right of return.
