The Bluetooth IoT sensor - roughness tester is used to determine surface roughness. The compact IoT sensor is a handheld device for mobile use. Due to the power supply via a powerful battery, it can be used directly on site. The IoT sensor is used in the laboratory, in production and everywhere where the roughness of surfaces is to be determined.
