Ultrasonic Non-Destructive Portable Hardness Tester 20N Resolution 1HV 0.1HRC
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.
Two Probes for Versatile Applications
Equipped with dual probes, the instrument adapts flexibly to a variety of hardness testing needs. Whether testing flat surfaces, small components, or irregularly shaped parts, it ensures accurate and reliable measurements.
Built-in Multiple Metal Materials
The instrument offers a selection of built-in metal materials to meet diverse measurement needs.
High Accuracy with Excellent Repeatability
A stable base ensures consistent probe positioning, delivering reliable results with high accuracy and repeatability.
Multiple Hardness Scales with One-Touch Switching
Built-in HV, HRC, HRB, HB, and other common hardness scales. Easily switch scales with a single button—no manual conversions needed.
User Calibration Supported
Supports calibration with standard hardness blocks to reduce system errors and ensure accurate measurements.
Bluetooth Connectivity with Mobile App
Connects to a mobile app via Bluetooth for multi-set data storage, viewing, and sharing.
Integrated Design for Easy Portability
The instrument features an all-in-one structure that is compact and lightweight. It can be easily operated with one hand, making it ideal for fast and efficient on-site hardness testing.
Built-in Data Storage
Stores up to 9 sets of measurement data for convenient review and comparison anytime.
Ergonomic Design for Comfortable Handling
Ergonomically shaped for a secure, comfortable grip and smooth operation—ideal for extended use without fatigue.
