CNC (Computer Numerical Control) hardness testers are advanced automated precision measuring instruments that integrate computer control, mechanical transmission, and hardness testing technology. Compared with traditional manual hardness testers, they feature high testing accuracy, good repeatability, and efficient batch testing capabilities, and can automatically complete multi-point testing, data recording, and report generation. These advantages make CNC hardness testers indispensable in mode

Levels are essential precision measuring tools designed to detect the horizontality (levelness) and verticality (plumbness) of surfaces, as well as to measure small angles of inclination. They are widely used in construction, mechanical manufacturing, interior decoration, precision equipment installation, and other fields. The performance and application scope of levels vary significantly depending on their structural design and working principles. This article classifies common types of levels,

Thickness gauges are essential precision measurement instruments widely used in manufacturing, material processing, and quality control across industries such as automotive, electronics, packaging, and aerospace. Their core function is to accurately measure the thickness of solid, liquid, or film materials, with working principles varying significantly based on the measurement method (contact or non-contact) and the physical properties of the measured material. This article elaborates on the wor
