This handy product is a mobile roughness tester in the Hommel Etamic series from Jenoptik. This mobile roughness tester is particularly well suited to take quick measurements on machines or in measuring rooms. Thanks to the diverse range of probes which can be replaced very easily, the mobile roughness tester can be used on a variety of surfaces. The mobile roughness tester also has a precision ground support bracket; this guarantees permanently stable workpiece support. If you want to measure the surface of a workpiece, which attaches higher, you can use your mobile roughness tester with the pull-out tripod legs adjusted to the respective height. In order to recognise the measurement surface better, the mobile roughness tester has a luminous prism with LED. The mobile roughness meter has five measuring programs and stores the measured data in the respective data storage. You can transfer them to your PC with the included USB cable as the data format is compatible with Windows. At the same time you start the charging function,when you connect your mobile roughness tester to the PC. To charge the battery without using a PC, you can connect the included power supply adapter to the USB cable, then your mobile roughness tester can be fully charged in just 4 hours.
