Portable Ultrasonic Hardness Tester with Hardness Scales HV/HRC/HRB/HRA/HS/HL/HB


Introduction:

Qualifications and Standards for the product:

  • GB/T 34205-2017 Metallic materials-Hardness testing-Ultrasonic contact impedance method
  • GB/T 33362-2016 Metallic materials-Conversion of hardness values
  • JJF 1436-2013 Calibration Specification of Ultrasonic Hardness Testers
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.
  • 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.

Bluetooth Communication:

  • The instrument has a built-in Bluetooth communication module,which can be connected to the instrument via a mobile phone APP.
  • Scan the QR code on the back of the instrument, and follow the prompts to download and install the corresponding "UT and HL"APP.
  • APP Connect device: Open the APP, search for the device and establish a connection according to the prompts.
  • Note: The APP does not support iOS. Please allow all permissions when running the APP.

Attentions:

  • When the instrument is turned on, the indenter should not touch any object to avoid affecting the calibration.
  • The minimum sample weight is 300g and the minimum thickness is 5mm. If the weight or thickness does not meet the requirements, it must be coupled to a firm support for testing.
  • The surface of the indenter and the sample should be clean. Surface dirt or coating will affect the measurement accuracy.
  • When measuring, the force should be steady and continuous to avoid the indenter sliding or swinging and affecting the measurement results.
  • When the indenter cover is removed, do not measure to avoid damaging the internal structure of the instrument.
  • When the battery of the instrument is empty, it should be charged in time.
  • If the instrument is not used for more than half a year, it needs to be charged regularly to prevent the battery from being over-discharged and damaged.
