Product Description

HST-U300 Portable Ultrasonic Hardness Tester

Product Description

Introduction:
There are many kinds of methods that can be used for hardness testing, and the more commonly used methods are Brinell, Rockwell, Vickers, and Leeb test methods. Among them, Brinell and Rockwell test force is large, indentation is large, and the surface damage of the sample is large, while Vickers adopts optical method to measure, which requires very professional technical personnel to operate, and can not directly test large workpieces; The ultrasonic hardness tester adopts the ultrasonic contact impedance method to compare and measure the styles, which has the advantages of high accuracy, fast speed, portability, and easy operation.
Measurable:
Hardness measurement of flange edge and gear root stampings, molds, thin plates, surface-hardened teeth, gear grooves, and taper parts,
Hardness measurement of shafts, thin-walled pipes and containers, hardness measurement of wheels and turbine rotors, hardness measurement of drill bit edges;
Hardness measurement of welding parts;
It can cover most of the hardness measurement of ferrous metals, non-ferrous metals and their alloys in industrial production. It is an ideal hardness testing instrument.
