NOVOTEST products

Concrete rebound hammer (sclerometer) – is a device for concrete and other building materials strength testing. The engineer Ernst Schmidt invented the construction of the sclerometer. The method is based on the impacting the impact plunger on the concrete surface with predetermined (normed) impacting energy and subsequent measuring of the height of the striker rebounding. The height of the striker rebounding will be proportional to the strength of concrete. The strength of concrete is determined with the calibration charts that are supplied with the instrument.

Steel Structure Analyzer NOVOTEST KRC-M2 is designed for measuring coercive force of metal products in accordance with IEC 60404-7 and is used for non-destructive testing of chemical-thermal, thermal and thermomechanical treatments, evaluation of mechanical properties and residual stresses.

Magnetic Flaw Detector (Magnetic Yoke) NOVOTEST MPD-DC applies in circumstances where the electric equipment mustn’t be used or prohibited by the rules. Device is used during magnetic particle inspection (where it is applicable) according to ASTM E 709, ASTM E 1444, ASME Section V Article 7 and MIL-STD-1949. Magnetic Flaw Detector NOVOTEST MPD-DC is used to detect surface and subsurface cracks of all kinds (flake, lack of fusion welded joints, tears etc.) in structures made of ferromagnetic materials. The device has two permanent magnets placed in a cylindrical shells, which are connected by a flexible magnetic wire, so it can be used for MPI of remote locations, corner welds and other products of various shapes and sizes.

Combined Hardness Tester NOVOTEST T-UD3 combines two methods of measuring hardness by an indirect method: Ultrasonic Contact Impedance (ASTM A1038) and Leeb (ASTM A956). This makes the device the most versatile portable device in the world.

The most popular portable hardness tester in the world is the Leeb hardness tester, however, there are tasks that using this method is very difficult or even impossible to solve. This is due to the physics of the method, which assumes the massiveness of the testing object, to ensure the inertness of the product when the Leeb’s impact body hits the surface with a given force. In order to solve a wider range of tasks on the rapid measurement of metal hardness, our company offers hardness testers that implement the method of ultrasonic contact impedance (UCI) in accordance with ASTM A1038. A vibrating rod (mechanical resonator) with a diamond tip acts as an indenter in these devices, when it indent into the material, the base frequency of the resonator changes, on the basis of which the hardness is calculated. This method has proven itself around the world and has been used in industry for over 50 years.

The most popular method in the world for testing the hardness of metals using a portable hardness tester is the Leeb method (ASTM A956). The so-called dynamic method for determining hardness is widespread due to its ease of use. The user does not need to have special skills and or knowledge in the field of hardness measurement, to carry out the measurement, it is necessary to charge up the impact body of the device’s probe, install the probe on the tested surface, press the release button of the probe and the hardness value will be displayed on the device screen.

NOVOTEST UCI probe Test Stand is used to measure the hardness of superthin sheet products. It can be used with any U?I probes which are equipped with NOVOTEST hardness testers. The point is that the thin wall of the product, when the UCI probe indenter is indented into it, does not provide sufficient impedance (it deforms under the load of the probe). In order to compensate for this deformation, this device is used.

The Combined Hardness Tester NOVOTEST T-UD2 combines the advantages of two methods: U?I  (ASTM A1038) and Leeb (ASTM A956), which makes it possible to solve almost any task of operational hardness testing. With this device, the user will be able to measure the hardness of both a large products with a rough surface and a small samples of complex shape and with a thin wall. This modification of the device has all functions for working with various materials and scales, which makes it an optimal device for non-destructive testing of metal hardness.
