SU-340T Introduction:

SU-340T Shorten Ultrasonic Hardness Tester is a special manual portable durometer with shorten probe HP-1T made by Sinowon group. It applies method of ultrasonic contact independence to make hardness testing at the spot.

SU-340T 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 inner wall, such as, engine, pressure vessel, pipeline, etc.

SU-340T conforms the standard ASTM A1038-2005, DIN standard DIN50159-1-2008 and China National standard GB/T 34205-2017.


SU-340T equips with short probe, it can non-destructively measure hardness of internal wall of tube, also called Tube Hardness Tester、Inner Wall Hardness Tester. 


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.
