JB-5C粗糙度輪廓儀廣泛應用于機械加工、汽車、軸承、機床、摸具、精密五金、光學加工等行業。儀器驅動箱提供了一個行程為100毫米長的高精度直線基準導軌，傳感器沿導軌作直線運動，位移量通過精密光柵位移傳感器進行數據采集。驅動箱可通過水平調節鈕作±10度的水平調整，并可分別通過控制箱的操作鍵或軟件界面進行水平和垂直方向的移動。儀器帶有電腦及專用測量軟件，在WINDOWS XP操作系統下的測量軟件操作直觀方便，功能豐富。

可測量各種精密機械零件的粗糙度和輪廓形狀參數。用擬合法可評定半徑、兩圓中心距角度、距離等。從而可測量直線度、凸度、溝心距、傾斜度、垂直距離、水平距離、臺階等形狀參數。

It is widely used in metrological departments of industries of autos, tools, bearings, Patterns, and optics for measuring profile and roughness of precision parts. The drive box is equipped with a straight-line guide of high accuracy traveling up to 100 mm. The displacement of the transducer moving along the guide collected with a precision grating system. The transducer is operated with either keys on the control box or the buttons on the window interface. The JB-5C software runs on Windows XP.

It is used to measure the form and roughness of profiles of precision parts. In addition to roughness, by fitting least-square line of nominal form, a variety of form parameters can be measured, such as radius, angle, straightness, convexity, vertical and horizontal distance, and distances between points, circles, and slots.
