SU-330C Lengthened Ultrasonic Hardness Tester

Mode/Code: SU-330C/#882-141C
Probe: Motorized Probe
Accuracy: ±3% HV, ±1.5HR, ±3%HB
Hardness Scales:: HV,HRC,HRA,HRB,HB


SU-300C Lengthened Ultrasonic Hardness Tester is a specialmanual portable durometerwith Lengthened probe HP-1C made by Sinowon group. It applies method of ultrasonic contact independence to make hardness testing at the spot.

SU-330C 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 deep hole of mold, the tooth of gear,inclined plane of rails, etc.

SU-330C conforms the standard ASTM A1038-2005, DIN standard DIN50159-1-2008 and China National standard GB/T 34205-2017.


SU-330C with extended probe used to test hardness of gear and deep hole specimen, under extreme space limitation or on the floor of grooves.


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.
