SONODUR 3 LITE LEEB- Essential Leeb hardness testing performance – proven quality for mobile applications.

Essential Leeb performance. Proven quality. The SONODUR 3 LITE LEEB is dedicated to pure Leeb hardness testing: focused, reliable, and uncompromising in accuracy. It uses the same high-quality probes and delivers the same precision as the SONODUR 3, while leaving out additional functions. Designed for straightforward operation, the LITE LEEB version omits camera features such as image storage, barcode naming, and DataMatrix adjustments.

UCI probe compatibility and Wi-Fi connectivity are not included; data transfer takes place via USB connection to your computer.

Alongside the Bluetooth-enabled probes, new wired Leeb probes now offer even greater flexibility. Choose from wired Leeb D and G or Bluetooth Leeb D, G, and DC probes.

Your advantages at a glance

User-friendly: The probes are easy to handle and can be mastered within minutes.
Fast measurement: Perfect for serial testing of larger components.
Comprehensive data storage: All relevant results can be saved, e.g. as Excel or TXT files.
Replaceable impact body: The Impact body can be replaced by the user at any time – no need to send the unit in.
Automatic Conversion to All Common Hardness Scales: Instantly displays results in any customer-specified scale (HV, HB, HRC, HRB, etc.) according to EN ISO 18265-2019, ASTM E140‑2019 and EPRI correlation P-91 2020 standards.

Portable Hardness Tester for Fast Metal Inspection

The SONODUR 3 Lite is a portable ultrasonic hardness tester designed for quick hardness testing of metal components. The device allows engineers to measure hardness directly on the part without cutting samples or sending components to a laboratory.

Portable hardness testing is useful when inspecting large, heavy, or installed components that cannot be moved to conventional hardness testing machines.

The SONODUR 3 Lite provides reliable hardness measurement for production inspection, maintenance checks, and quality control applications.

Ultrasonic Hardness Testing Using the UCI Method

The SONODUR 3 Lite operates using the UCI (Ultrasonic Contact Impedance) hardness testing method. This method measures the change in ultrasonic frequency when a vibrating probe is pressed against the surface of a metal component.

The system converts this measurement into hardness values such as:

Vickers (HV)
Rockwell (HRC / HRB)
Brinell (HB)

Because the indentation produced by the probe is extremely small, ultrasonic hardness testing is suitable for finished or precision components where surface damage must be minimal.

Typical Applications of Portable Hardness Testing

Portable hardness testers are commonly used in manufacturing and inspection environments where fast hardness verification is required.

Typical applications include:

hardness testing of heat-treated components
inspection of forged parts and machined components
hardness verification of gears, shafts, and structural parts
weld inspection and heat-affected zone testing
on-site hardness testing during maintenance inspections

These applications require reliable hardness measurements without removing the component from service.

Industries Using Portable Hardness Testers

Portable ultrasonic hardness testers are used across many industrial sectors where material strength and quality must be verified.

Common industries include:

automotive component manufacturing
forging and metal forming plants
aerospace component production
steel and metal processing industries
heavy engineering and power generation equipment

In these industries, hardness testing helps ensure that materials meet design specifications and quality standards.

Advantages of the SONODUR 3 Lite

The SONODUR 3 Lite provides several advantages for portable hardness testing applications:

fast hardness testing directly on metal components
portable device suitable for shop floor and field inspection
minimal indentation on finished surfaces
suitable for testing small areas or complex geometries
reliable hardness measurement for quality control

These advantages make portable ultrasonic hardness testing a practical solution for industrial inspection and production quality control.

Discuss Your Hardness Testing Application

If your inspection process requires portable hardness testing for metal components, the SONODUR 3 Lite provides a reliable solution for on-site hardness measurement.

Our engineers can help determine the appropriate configuration based on the material type, component geometry, and hardness range required.
