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-300Mconformsthe standard ASTM A1038-2005, DIN standard DIN50159-1-2008 and China National standard GB/T 34205-2017.
