FAQs

1. What materials can be tested with the Portable Leeb Hardness Tester ?

The Portable Leeb Hardness Tester can test a diverse range of metallic materials, including forged steel, cast steel, stainless steel, grey cast iron, ductile iron, copper alloys, aluminium alloys, bronze, and pure copper. It provides reliable readings by converting the measured values into multiple standardized hardness scales such as , HB, , , HV, and . This versatility makes it suitable for evaluating both ferrous and non-ferrous components. The dual testing modes enhance its compatibility with different sample geometries. As a result, it is highly adaptable across industrial quality inspection workflows.

2. Does the Portable Leeb Hardness Tester support multiple impact devices?

Yes, the Portable Leeb Hardness Tester supports up to seven different types of impact devices, which broadens its testing capability across various material types and surface conditions. The device is designed with automatic recognition for these attachments, eliminating the need for manual calibration after each switch. This feature ensures quick transitions between testing modes and saves valuable time during large-scale or multi-material inspections. Each impact device is tailored for specific applications such as narrow spaces or curved surfaces. This makes the highly efficient for comprehensive field and production testing.

3. Can the Portable Leeb Hardness Tester print test results?

Yes, the Portable Leeb Hardness Tester is equipped with a built-in thermal printer that allows users to print test results immediately after measurement. The printer uses standard thermal paper rolls and operates with minimal noise, providing a user-friendly and efficient documentation solution. Printouts include all relevant parameters such as test date, material type, hardness value, and impact direction. This feature is particularly useful in environments where traceability and on-the-spot verification are essential. It ensures quick sharing and archiving of test records in industrial, research, or service settings.

4. Is data transfer available in the Portable Leeb Hardness Tester ?

Yes, the Portable Leeb Hardness Tester includes a 2.0 interface that facilitates fast and reliable data transfer to computers or other storage devices. Users can export test results in bulk for further analysis, reporting, or record-keeping. Optional PC software enhances this functionality by enabling statistical review, data sorting, and customized reporting formats. This capability improves workflow efficiency in quality control departments and reduces the likelihood of manual entry errors. The port also supports firmware updates, ensuring the device remains compatible with the latest features.

5. How long does the battery last in the Portable Leeb Hardness Tester ?

The Portable Leeb Hardness Tester is powered by a 7.4V 1500mAh rechargeable lithium battery, providing up to 300 hours of continuous operation on a single charge. This extended battery life ensures uninterrupted testing during prolonged on-site or field operations without frequent recharging. The battery is optimized for energy efficiency, supporting the device's built-in printer and data storage capabilities. It is especially beneficial in industrial environments where stable power sources may not be readily available. The long-lasting performance enhances mobility and productivity for engineers and inspectors.
