The Institute of Applied Physics offers consumers a portable hardness tester TPTs-7 for non-destructive measurement of the hardness of products made of carbon structural steels on scales and assessment of the hardness of other metallic materials: alloy steels, cast irons, non-ferrous metals and alloys under a manufactoring agreement and is looking for partners interested in technology transfer under a license agreement and/or to conclude a distribution services agreement.

The principle of operation of the device is based on the use of the dependence of the shock pulse parameters on the elastic-plastic properties of the controlled material. When performing a measurement, a test impact is applied to the surface of the inspected product with an indenter. The sensor, which is part of the hardness tester, registers the parameters of the movement of the indenter, forming a measuring signal. In the electronic unit, based on the received signal, the value of the hardness of the material is determined.

* TPC-7 has small overall dimensions and weight.
* The use of a hardness tester to control products without lapping to a massive base, starting from a mass of 1.5 kg.
* Automatic calculation and display of the arithmetic mean of the measurement results.
* Transfer to all common scales (HB, HRC, HV, HRB, HS, Rm).

* Measurements can be taken in any orientation with automatic reading correction.
* Hardness measurements on products with wall thicknesses of 5.5 mm or more.
* Low impact energy (~2 mJ) allows the hardness tester to be used for inspecting finished mating surfaces.
* The TPC-7 allows for measurements in hard-to-reach areas, such as gear teeth.

The device is included in the State Register of Measuring Instruments of the Republic of Belarus.

The TPC-7 hardness tester also offers a number of advantages, including affordability, ease of use, reliability, and adaptability to local conditions. Its main differences from foreign counterparts include localized production, affordability, and a focus on the specific needs of the regional market. This makes the TPC-7 an attractive choice for companies seeking a reliable and cost-effective hardness testing instrument.
