Product introduction: JB - 4 C precision roughness meter is a kind of high precision contact pin type surface roughness measuring instrument, the instrument can be on the plane, inclined plane, cylinder, inner hole surface, deep groove surface, circular arc surface and spherical parts surface roughness are tested, and the shape of the surface roughness and contour parameters such as the peaks and troughs of measurement, also can measure the workpiece TP stage. The instrument is easy to use and the measuring precision is high, repeatability is stable.The instrument is equipped with computer and special measuring software. Advanced noise-free mechanical positioning device can be used to select different locations of the parts under test and set various measuring lengths for automatic measurement. The sampling data in the evaluation section reaches 4000 points.All the measurement data and curves can be displayed or printed out on the screen, so it is widely used in the auto supporting industry, mechanical processing, precision tool molds, scientific research institutions, universities and other major industries. The instruments meet the requirements of national standards GB/ t3505-2000, GB/ t6062-2001, GB/ t10610-1998, and international standards ISO5436, ISO11562 and ISO4287. JB-4C precision roughness instrument is a stylus surface roughness measuring instrument, which can test the roughness of various parts. The roughness of plane, bevel, outer cylinder, inner hole surface, deep groove surface, arc surface and sphere can be tested. And realize many parameter measurement. This instrument is manufactured according to GB/ t3505-2000, GB/ t6062-2001, GB/ t10610-1998 national standard and ISO5436 and ISO11562 international standards. The device is composed of granite plate, worktable, sensor, drive box, monitor, computer and printer, etc. The drive box provides a high-precision linear reference guide with a range of 60 mm. The sensor moves in a straight line along the guide. The instrument is equipped with computer and special measuring software. It can select different locations of the parts under test and set various measuring lengths for automatic measurement. The sampling data in the evaluation section reaches 3,000 points. It can display or print contour, various roughness parameters and supporting length rate curve of contour. Advantage: 1. The roughness contour meter adopts automatic lifting system up and down 2. The step motor drive is not air floatation. 3. Rough, contour measurement only needs to replace the touch pin, not the sensor 4. The test results can be displayed in word 5. The contour image can be converted to CAD output Technical parameters: Type：JB-4C For Roughness measuremen Evaluation Parameters：Ra,Rz,Rt,RS,RSm,Rp,Rv,Rmax,Rq,D,Pt, Lr,Ln and Rmr (Tp) curves, etc. Vertical Magnification：10-500000 automatic adjustment Roughness range：Ra 0.01-10 μ m Sampling length：L: 0.08 ,0.25, 0.8, 2.5 mm Evaluation length：Ln: 1L, 2L, 3L, 4L, 5L Selectable Sampling points：4000 points Resolution：0.001 μm Indication error：± (5 %+4nm) Repetition error：± 3 % Max. specimen height：300mm Application：planar, incline, cylinder, circular and spherical parts, grooves and bores.
