Abstract

This invention relates to an apparatus and a method for measuring hot hardness (HIT) of materials. The apparatus comprises a main frame (V) and a displacement gauge (9) connected to the frame (V) by spring elements (12), and the gauge (9) is provided by a core rod (91) biased against the frame (V) by a mounting spring (6). A measuring frame (1) having an inner surface (11) for fixing a test piece (5) is mounted on the frame (V), and a measuring rod (2) is attached to the rod (91). A measuring tip (4) is connected to the measuring rod (2), and a furnace (8) surrounding at least the inner surface (11) is arranged around the measuring frame (1), and a thermocouple (13) for measuring the temperature of the test piece (5) is provided, wherein the measuring rod (2) and the measuring frame (1) are made of the same material. (Fig. 1.).
