The ARW-BT300 portable roughness tester is a high-precision instrument for measuring surface roughness. Its innovative construction features allow it to be used in various applications where other instruments fail to satisfy. It can be used on a variety of machining and surfaces, not only flat but also external conical, external cylinder, internal, curves, through holes, grooves and more. Numerous functions, including the large color graphic touch screen display and the innovative Bluetooth interface with APP connection, make it a practical, modern and reliable instrument.
