TJD520 Portable Surface Roughness Tester

Portable Surface Roughness Tester TJD520 is a high accuracy instrument for measuring surface roughness. It can be used on variety of machining parts and operates on various surfaces, not only flat but also outer cone, outer cylinder, curved, pinholes, grooves, recesses grooves and axle etc.   Application Portable Surface Roughness Tester TJD520 allows surface roughness measurement both on metal and non-metal workpieces. It is suitable for machining and manufacturing, quality control, inspection departments, especially for measurement on large and heavy workpiece, assembly line on site. The JD520 is a Non Destructive Testing instrument, damage won’t caused to testing piece.   Main Feature Mechatronics and ergonomics design, small size, light weight, easy to operation The stylus drive unit can be stored within the main unit for standard measurement, or separated from the display unit by using the supplied cable which allows more flexible measurement in any orientation. The driver can be separated and reattached in one simple step. DSP chip control and data processing, high speed, low power consumption 22 Parameters: Ra ,Rz, Rq, Rt, Rp ,Rv, R3z, R3y, Rz(JIS), Rs, Rsk, Rsm, Rku, Rmr, Ry(JIS), Rmax,RPc, Rk, Rpk, Rvk, Mr1, Mr2 Measurement range up to 160μm (can be optional to 320μm) 5 inches color graphic TFT touch screen, wide viewing angle, excellent readability and an intuitive rich display, it includes a backlight to improve visibility in dark environments Can be operated using buttons or touch screen It provide Bluetooth Capability , support wireless connection with mobile and mini printer.
