The Roughness Tester PCE-RT 1200-ICA is used to determine surface roughness. The compact roughness tester is a handheld device for mobile use. Due to the power supply via a powerful battery, it can be used directly on site. The roughness tester is used in the laboratory, in production and everywhere where the roughness of surfaces is to be determined. The measured values are displayed on the clear and user-friendly OLED display directly on the measuring device. In addition, the roughness tester has a storage option for up to 20 measured values, which can later be read out via the micro USB interface. For this purpose, the measurement software can be used, and a USB cable is included in the delivery. The built-in rechargeable battery is also charged via the micro USB interface. The above mentioned measurement software is particularly suitable when measurement series are pending. The data is then transferred to the software and can be evaluated directly on the screen.
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.
