UH300 Ultrasonic Hardness Tester

Applications

• Performs precise hardness testing on challenging components such as flange edges, gear roots, stamping parts, molds, thin plates, case-hardened gear teeth, grooves, and tapered sections.

• Ideal for measuring the hardness of axles, thin-wall pipes, and pressure vessels without causing damage.

• Effectively conducts hardness tests on large components like wheels and turbine rotors on-site.

• Enables accurate hardness verification of cutting tool edges and other hardened surfaces.

• Specifically suited for hardness testing of weld seams and Heat-Affected Zones (HAZ) to assess structural integrity.

• Capable of measuring hardness in deep holes, on concave/convex surfaces with large radii, and on irregular Widely applicable for hardness testing of most ferrous and non-ferrous metals and their alloys commonly used in industrial production.

Functional characteristics

• Ergonomically designed with an innovative sculpt and exquisite craftsmanship, ensuring a comfortable grip and stable operation during prolonged use.

• Features a high-resolution 3.5-inch color LCD screen (320x480) that delivers clear, information-rich graphics and readings, ensuring excellent visibility.

• Intuitive menu-driven operation with a minimal number of keys and full English display, making it simple to operate with minimal training.

• Easily adapts to materials with different elastic moduli through a quick and simple single-point calibration.

• Advanced multi-point calibration function allows for calibration to any hardness standard. Even for materials without a standard conversion table, users can create a custom curve using 2-10 samples of varying hardness.

• Delivers high accuracy meeting national standards (GB/T-34205, JJF1436, JB/T9377), with tolerances of ±3% HV/HB and ±1.5 HR (when used with a test stand).

• Leaves an ultra-tiny indentation, significantly smaller than Leeb hardness testers, making it a near-non-destructive method.

• Offers rapid testing speed, providing results within 2 seconds for efficient high-volume inspections.

• Its portability and speed make it ideally suited for assembly line quality control, offering advantages over bulkier Leeb testers.

• Includes 50 sets of data storage capacity with timestamp functionality for traceability.

• Allows for 360° measurement without the need for positional correction, simplifying testing on complex geometries.
