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.
– Very compact
– Easy to handle
– A large OLED display
– 4 measurable parameters of roughness
– The probe of the roughness meter consists of a high-quality diamond
– The display of the roughness meter outputs the measured values in tabular
form
– The measured values can also be output by the roughness meter as a graph
– A micro-USB interface for online data transmission to a PC (for example
useful for serial measurement or
laboratory measurement)
– An internal rechargeable battery (3000 measurements with one battery charge
(Li-ion))
