Portable roughness tester


RT90G roughness tester is unique in its category because it features a built-in calculation unit and measurement procedure, thus being the first ''All-in-one’’ roughness tester. Extremely compact and easy to handle, it conveniently allows positioning also on large size pieces, thanks to built-in micrometrics with 100 mm range. The shiny 3.7’’ colour touchscreen display combined to the icon interface, allows the operator to set the measurement parameters, moving on the piece and carrying out the analysis quickly. The results obtained and the relative tolerances are immediately displayed and can be downloaded on PC or printer using the external printer. The internal reference allows to perform analyses also on W waviness parameters, while the bistable pick-up holder allows measuring with one simple gesture, with or without skid, as required.
