Hao goods roughness parameters consulting 13,698,986,822 pocket surface roughness HPNDT110 given in line with GB / T 3505-2000 "predicate Geometrical Product Specifications Surface texture surface structure contour method, definitions and parameters", in line with GB / T 6062-2002 "Geometrical product specifications (GPS) Surface texture Profile method of contact (stylus) instruments nominal characteristics." Scope: metal and non-metal parts of the surface roughness of the test to detect for a variety of machined parts, machinery processing and manufacturing, testing, inspection and other departments, especially for large parts and production lines of the site inspection, and testing, measurement, inspection and other departments to go out test, will not damage the workpiece. Measurable plane, diameter greater than 20mm (experience) of the outer surface of the cone, and also measure the length and width of the groove is greater than 80 × 30mm. Unique features: rigorous temperature and humidity test, high temperature and high humidity environment adaptation, especially in the southern humid climates measured values ??are not affected. Service: The user presses the "manual" normal operating conditions, the Company products replacement within three months, two years free maintenance (but wearing consumable parts except probe sensor cable), and is responsible for the product life-long maintenance.
