The DHT400 PLUS Portable Digital Hardness Tester is an advanced instrument that utilises the LEEB rebound measuring principle (174HL-960HL). It guarantees measurements in any direction, supporting materials such as steel, cast iron, aluminium, brass and copper. Allowable roughness ranges from 2μm (probe D) to 7μm (probe G), with a minimum thickness of 3 mm. It includes an optional impact device (DL, C and G) and offers accuracy of ±0.5% at HL=800. It has unlimited memory connected to a smartphone or tablet via Bluetooth and runs on a 3.7V rechargeable battery. The 128x64 OLED display and the weight of 0.12 kg make it easy to use in extreme conditions.

The portable digital durometer measures the hardness of materials using the LEEB rebound principle, with a range from 174HL to 960HL. It is an essential and versatile tool for industries such as metallurgy and mechanics, ensuring quick and precise measurements.
The use of the portable digital durometer is simple and intuitive, thanks to its compact size and a weight of only 0.12 kg, making it ideal for on-site measurements or in challenging industrial environments. It operates reliably even in extreme conditions, with an operating temperature range from -20°C to +50°C. The device is powered by a 3.7V rechargeable battery, ensuring long autonomy. The 128x64 OLED display provides clear reading of the results even in low light conditions.
The operation of the durometer is based on several optional impact probes (DL, C, and G), which allow the device to be adapted to different materials and surfaces to be tested. The probes can be selected based on the roughness and thickness of the material. For example, the D probe is ideal for materials with a maximum roughness of 2μm, while the G probe is suitable for surfaces with roughness up to 7μm. The durometer is capable of measuring the hardness of materials such as steel, cast iron, aluminum, brass, and copper, covering a wide range of applications.
This tool stands out for its precision and repeatability, with an accuracy of ±0.5% at HL=800. Additionally, it features unlimited memory, which connects to smartphones or tablets via Bluetooth, allowing real-time data storage and analysis. The Bluetooth connectivity also enables data to be sent to a printer for immediate printing of results.
The measuring range of the portable digital durometer varies from 174HL to 960HL, covering a wide range of metallic materials. Besides the LEEB unit, the device also supports other hardness parameters such as HRB, HRC, HV, HB, and HS, as well as tensile strength (UTS) for steel, with a range from 370 to 2000 N/mm². Thanks to this versatility, the durometer can be used to test materials such as cast steel, alloy tool steel, stainless steel, gray cast iron, nodular cast iron, aluminum, bronze, and copper.
To ensure accurate hardness measurement, it is essential that the sample has a minimum thickness of 3 mm, while for the G impact probe, a minimum of 10 mm is required. The durometer also supports surfaces with a maximum roughness of Ra 10, ensuring measurements are always precise even on surfaces that are not perfectly smooth. For smaller samples weighing less than 2 kg, coupling is required for reliable measurements, while samples between 2 and 5 kg should be placed on a solid base.
The main application of the durometer is found in the metallurgical industry and in all sectors where a rapid and precise assessment of the hardness of metallic materials is needed. Its ability to operate in any direction, without the need to orient the device, makes it ideal for in-situ measurements, in difficult environments, or on large structures where access to surfaces may be limited. The use of the durometer is essential for quality control, industrial maintenance, and verifying the technical specifications of materials in production.
