Introducing our advanced surface roughness tester, a state-of-the-art device designed for precise and reliable evaluation of surface texture. Technical parameters are as follows: Parameters include RA, RZ, RY, RO, RT, RP, RV, RMAX, R3Z, RSK, RS, RSM, and RMR. Measurement ranges for RA, RZ, RY, RT, and RP span from 0.005 to 16μm, while RV, RMAX, and R3Z measure between 0.02 and 160μm. The innovative error correction feature enables one-button measurement correction, ensuring accuracy with a resolution of 0.001μm. Filter options include RC, PC-RC, GAUSS, and D-P, and users can choose from sampling lengths of 0.25mm, 0.8mm, and 2.5mm. The evaluation length offers flexibility with options of 5L, which can be adjusted within a range of 1 to 5L based on selected sampling length. Drive stroke ranges from 1.25mm to 17.5mm, with indication error maintained at or below ±10% and variation less than 6%. This tester is compatible with a wide array of workpieces, including large flat surfaces, thin shafts (with fixture), curved surfaces, and other specialized forms. The clear LCD display is user-friendly and powered by a rechargeable lithium battery. Included with purchase are essential accessories, such as the main unit, test block bracket, standard test block, standard sensor, height adjustment bracket, and probe protective cover. The device measures 157x62.6x45 mm and weighs 456.8g. Note: This product is not compatible with 110V voltage. Ensure compatibility before ordering to avoid the need for a separate transformer.
