The ultrasonic hardness tester AG-530 adopts the ultrasonic contact impedance method for comparative measurement of samples, which has high accuracy, fast speedAdvantages such as portability and easy operation. The ultrasonic hardness tester AG-530 can measure the stamped parts, molds, thin plates, and surface hardened teeth of flange edges and gear rootsHardness measurement of gear grooves and taper parts; And hardness measurement of shafts, thin-walled pipelines, and containers; Hardness measurement of wheels and turbine rotors; The cutting edge of a drill bitHardness measurement; Hardness measurement of welding parts; It can cover the hardness measurement of the vast majority of black metals, non-ferrous metals and their alloys in industrial production.
