Motorized Ultrasonic Hardness Tester SU-300M 882-141M
SU-300M Introduction:
SU-300M Motorized Ultrasonic Hardness Tester is a popular portable durometer made by Sinowon group. It applies method of ultrasonic contact independence to makehardness testing at the spot or in the laboratory.
SU-300M is a perfect portable durometer for hardness testing about the coating and plating, it can measure the hardness of chrome, copper plating, carburized layer andNitriding layer effectively.
SU-300M is a NDT durometer due to the contact indention is too small to observe, it is one of the excellent solution totest hardness of finished products, such as, the mold, gear, shaft, rod, screw, rails, etc.
SU-300M can not only work with the motorized probes, but also work with the manual probes, which is able to meet the different application in light of different condition of surface roughness.

SU - 300M can measure the vast majority of the hardness of ferrous, non-ferrous metals and the alloys in industrial production, and it is a kind of perfect testing instruments. By comparing method, it can measure the material hardness of HRA, HRB, HRC, HV, HBW, HS and steel hardness at production line and laboratory.
Motorized ultrasonic hardness tester SU – 300M can be added with manual probe HP - 1 k, HP - 2 k, HP - 5 k, HP - 10 k to measure rough samples.
SU - 300
can measure the hardness of coating, also known as the coating hardness tester, the portable Vickers coating s hardness tester.

2、Amazing Design, Exquisite Workmanship
Innovative use of ergonomic, streamlined design, exquisite metal exterior, metal and glass panels presented a smooth flowing, environmentally friendly yellow screen buttons, and side power supply control switch, it has been such a high level of design and manufacturing process; it is all that achieved the prosperous Ultrasonic Hardness Tester incredible perfect look.
