LS256 Portable Ultrasonic Hardness Tester Rockwell Hardness Gauge Dual Probe 5mm
Description；
Linshang LS256 Ultrasonic Hardness Tester uses the Ultrasonic Contact Impedance (UCI) method for hardness testing, capable of measuring a wide range of metal materials. Its minimal indentation ensures almost no surface damage, making it suitable for coatings, plating, and hardened layers as well. Multiple hardness scales are built in, allowing easy conversion between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), and Rockwell (HRA, HRB, HRC).
Features: - Compact all-in-one design, ready to use in 1 second. - Dual probes measure both flat and irregular surfaces. - Non-destructive testing with minimal indentation using UCI. - Built-in selection for testing multiple metal materials. - High-precision measurement up to ±4%HV. - Bluetooth-enabled with app connectivity and user calibration. - Supports multiple hardness scales: HL, HV, HB, HS, HRA, HRB, HRC.
