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 make hardness 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 conformsthe standard ASTM A1038-2005, DIN standard DIN50159-1-2008 and China National standard GB/T 34205-2017.

Highlighting Characteristics:

Perfect Accuracy——±3% HV, ±1.5HR, ±3%HB.

Microscopic Indentation—— Only high-power microscope can observe the indentation.

Quick Measurement——Result in 2 seconds.

Large LCD Display——Directly display measurement result, times count, maximum, minimal, average and deviation. 

Friendly Operation——Operate well after short training.

Promised Warranty——2-Year warranty for main unit (Excludes Probe).

Mass Storage——Save 1000 groups measurement data.

Simple Calibration——Save 20 groups calibration data for invoking, improve calibration efficiency.
