Metal testing has never been more convenient. With the Leeb hardness tester, accurate hardness readings are now available on the go. The MR‑LH70 model offers a perfect blend of precision and portability. This makes it popular across industries like manufacturing, automotive, and construction.
Portable Precision in Every Test
The Leeb hardness tester MR‑LH70 uses a rebound principle. It measures hardness based on the impact and rebound velocities of a test impact body. That means accurate results without bulky stationary machines. For professionals needing quick spot checks or multiple site inspections, this portability is a key advantage.
This portable unit is rugged and ready for field use. It features a protective case, rubber bumpers, and a dust-resistant cover. The compact device measures just 185×98×42 mm and weighs about 0.35 kg—easy to carry but built tough.
High Accuracy, Anywhere
Despite its compact size, the Leeb hardness tester delivers results that rival fixed laboratory testers. It supports Rockwell, Brinell, and Vickers scales, covering ranges like 20–70 HRC, 20–650 HB, and 230–940 HV. Accuracy is within ±0.2 HRC or ±3 units for Brinell and Vickers under recommended limits.
It calculates hardness using up to 20 consecutive measurements and provides average, minimum, and maximum values. It also has built-in false-value detection to ensure reliability.
Smart Display & Built-In Data Storage
MR‑LH70 includes a vibrant 3.5‑inch color TFT display. The interface is user-friendly and simple to operate. It supports multiple languages—English, Russian, and Ukrainian—and allows custom calibrations beyond standard scales.
A built-in database stores over 1,000 readings. It can generate reports and export data via USB. This makes managing test data and analysis easy and efficient.
Calibration and Compatibility
The tester comes pre-calibrated for steel, cast iron, stainless steel, aluminum, bronze, brass, and copper. Calibration can be extended to other materials if reference samples are available. The device accommodates dynamic sensors Type D or G, depending on surface texture.
Surface roughness matters: a 3.2 Ra is ideal for Type D sensors, and up to 7.2 Ra for Type G. A minimum flat area of 14 mm in diameter is required for accurate readings. Following these guidelines ensures consistent test results.
Versatile Applications
MR‑LH70 suits a variety of tasks: hardness checks on carbon steel, stainless steel, heat-resistant alloys, galvanized coatings, aluminum, copper, and more. It handles structured surfaces, welds, compact parts, and thin-walled components with ease.
The portability allows inspections on-site, in workshops, or in production areas. It’s a tool that fits well into any quality control workflow.
Built to Last
Equipped with a rechargeable Li‑Po battery giving around nine hours of runtime, the unit operates well between –20°C to +45°C. It’s impact-resistant and designed for professional environments.
Given its rugged build and long operational life, the Leeb hardness tester MR‑LH70 is a dependable companion for field or lab testing.
METERDI: A Brand You Can Trust
METERDI serves a range of professionals—electrical engineers, industrial manufacturers, and environmental agencies. Our instruments, including multimeter clamp options, digital meters, and sound level testers, are recognized globally for precision and quality. The same excellence applies to their hardness testing line.
The company values integrity, innovation, and excellence. Dedicated support and continuous product improvements reinforce their reputation in test and measurement tools.
Supporting Tools: Multimeter Clamp Use
While testing hardness, other tools like a multimeter clamp may be needed. This tool helps technicians check equipment voltage or current before testing metals. The multimeter clamp enables safe diagnostics and ensures accurate test conditions.
Tech teams frequently pair a multimeter clamp with the Leeb hardness tester to ensure equipment power is stable, especially in automotive or industrial plants. This inspection helps validate that electrical systems won’t influence hardness readings.
Why Buy Online?
Ordering a Leeb hardness tester online gives access to verified sellers and clear product details. The MR‑LH70 is often listed with a price of ₹250,000 plus GST, offering value compared to its original rate.
Buying online ensures easy access to specifications, user manuals, and after-sales support. It also helps compare with other portable testers or tools, like a multimeter clamp, to meet specific testing needs.
Ease of Use
The Leeb hardness tester is built for simplicity. Test steps are clear: place the impact body, trigger the test, and view results instantly. All data and calculations are handled internally.
Results appear in the selected hardness scale immediately. The tester can display live graphs, average values, and detect errors automatically. No advanced training is required—just a basic understanding of hardness scales.

Comparison with Other Methods
Traditional hardness testing methods often need bench-mounted machines and surface preparation. This requires time, lab space, and transport of samples.
On the other hand, the Leeb tester streamlines the process: fast readings, mobile testing, and dense data management. It reduces downtime and minimizes sample handling errors.
Recommendations for Optimal Use
Ensure surface conditions meet roughness requirements. Calibrate the tester with certified blocks periodically. Use the appropriate sensor based on surface finish and material type.
Before testing, perform electrical checks with a multimeter clamp to ensure test conditions are safe. Following these steps ensures reliability and consistency.
