LS256 Ultrasonic Hardness Tester
Integrated design + Two probes
Portable size, easy to carry
Small indentation, non-destructive measurement
Easy operation for measuring flat, small, or irregular parts
High precision, good repeatability
Ultrasonic hardness tester uses the ultrasonic contact impedance method to measure various metal materials. With minimal surface damage, it is ideal for testing metal coatings, plating, and hardened layers. It supports multiple hardness scales, including HL, HV, HB, HS, HRA, HRB, and HRC.

Features
Minimal Indentation for Non-Destructive Testing
Utilizing the ultrasonic contact impedance (UCI) method, the test leaves only tiny indentations, preserving the surface of precision or finished parts while delivering accurate hardness measurements.
Measurable Ultra-Thin Materials
The instrument can also perform accurate and non-destructive measurements on ultra-thin workpieces (if the sample does not meet the minimum mass of 300g and a minimum thickness of 5mm, grease can be used to couple the sample to a sturdy support for testing).
More Accurate Testing with a Hand Pressure Test Stand
A dedicated hand pressure test stand is available for users to choose from, making measurements more convenient and offering better accuracy and repeatability.
Simple Operation with Rapid Measurement
No complex settings required — just power on and test. Results are displayed in 1 second, ideal for batch inspections and fast-paced quality control.
High Accuracy with Excellent Repeatability
A stable base ensures consistent probe positioning, delivering reliable results with high accuracy and repeatability.
