Dynamic hardness tester TKM-359C “Maximum”
Description
The dynamic hardness tester TKM-359C "Maximum"manufactured by NPP Mashproekt is a high—precision instrument for measuring the hardness of metal and alloy products, including quality control of heat treatment, hardening of HDPE, evaluation of mechanical strength in laboratory, industrial or field conditions.
The device performs non-destructive product quality control in metallurgy, mechanical engineering, aircraft, shipbuilding, energy, nuclear, and oil and gas industries.
The principle of operation is the Lieb method, in which the ratio of the rebound velocity to the fall velocity of the carbide-tipped indenter depends on the hardness of the test material.
The TKM-359C Maximum hardness tester kitis designed for use in difficult production and field conditions. The device with accessories is supplied in an impact-resistant suitcase; it includes additional sensors, a "Z-359" attachment for sensor positioning, and an additionalconnecting cable, HB hardness test sample.
The TKM-359C Maximum hardness tester performs hardness testing of
- all major types of metals and alloys without additional calibrations:
- structural and tool corrosion-resistant, heat-resistant, stainless steels and alloys,
- alloys of non-ferrous metals, cast iron, aluminum, bronze, brass;
- surface-hardened and hardened products (HDPE hardening, etc.);
- products of complex configuration (gear teeth, pipes, shafts);
- heavy and large-sized objects with a rough surface (gas pipelines, rails, structural parts).
Hardness tester TKM-359C "Maximum" Maximum is included in the State Register of SI of the Russian Federation. Complies with the requirements of TR CU 004/2011 and TR CU 020/2011.
