Ultrasonic Hardness Tester SU-300M

Highlights :

● 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.


– It applies ultrasonic resistance method to do comparison measuring.

– It not only bears the international mainstream brand ultrasonic features such as: microscopic indentation, quick measurement and perfect accuracy, but also adopts the design of streamlined ergonomics and high-definition color LCD screen as  terminal display, which makes the man-machine interface more friendly and more easy for non professional operators.

– It also passed the ISO9001:2008 certification and won the title “contract first, credit first” in guangdong province and was identified as dongguan private high-tech enterprises in 2013.

– Ultrasonic hardness tester applies foreign technology and imports the original parts then assembles in China.

– Product quality completely accords with American standard ASTM A1038-2005, Europe standard DIN50159-1-2008 and the Chinese industry standard JB/T9377-2010 technical requirements.
