CR100 Economic Surface Roughness Tester

CR100 Pocket Surface Roughness Tester is a new intelligent instrument dedicated to measuring the surface roughness of the processed parts. This instrument integrates today's microprocessor technology and sensing technology. With advanced microprocessor and preferred highly integrated circuit design, it forms an ultra-small system structure that meets the development trend of today's instruments and completes the collection of roughness parameters. , Processing and display work. NDT110 is suitable for processing industry, manufacturing, inspection, commodity inspection and other departments, especially for on-site inspection of large workpieces and production lines, as well as inspections of inspection, metrology, and commodity inspection departments.

       The parameters given by this instrument are in accordance with GB / T 3505-2000 "Product Geometry Technical Specification Surface Structure Profile Method Surface Structure Terms, Definitions and Parameters", and GB / T6062-2002 "Product Geometrical Technical Specification (GPS) Surface Structure" Nominal characteristics of contour contact (stylus) instruments.  

Main functions :

²        测量参数; Choice of 2 measurement parameters;

²        Selectable sampling length;

²        进行数据处理和计算; Adopt high-speed DSP processor for data processing and calculation;

²        Dot matrix LED liquid crystal display, high brightness, no viewing angle, wide temperature;

²        With calibration function;

²        Automatic shutdown function and low power consumption software and hardware design make the instrument work longer;

²         Two charging methods, the computer's USB port for charging, can work while charging, convenient and quick;

²        ,有效的保护了传感器测头,保证了测量的精度。 The sensor probe has a protective door , which effectively protects the sensor probe and ensures the accuracy of the measurement.

The surface roughness sampling length is a length of a reference line specified for judging and measuring the surface roughness, and it is sampled in the overall direction of the contour. Because the processed surface has different degrees of non-uniformity, in order to fully and reasonably reflect the roughness characteristics of a surface, it is stipulated that an appropriate sampling length is selected during evaluation.
