Manual Ultrasonic Hardness Tester SU-300H
SU-300H Introduction:
● SU-300H Manual Ultrasonic Hardness Tester is a classical portable
durometer made by Sinowon group. It applies method of ultrasonic
contact impedance to make hardness testing at the spot or in the
laboratory.
● SU-300H is a NDT durometer due to the contact indention is too
small to observe, it is one of the excellent solution to test
hardness of finished products, such as, the mold, gear, shaft, rod,
screw, rails, etc.
● SU-300H can not only work with the manual probes, but also work
with the motorized probes, which is able to meet the different
application in light of different condition of surface roughness.
● SU-300H conforms the 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.
