Can the Vickers hardness tester change temperature?

The temperature cannot be changed. An increase in the temperature of the Vickers hardness tester will cause the measured hardness value to be lower, and a decrease in temperature will cause the measured hardness value to be higher, so the temperature cannot be changed. The Vickers hardness tester is a high-tech product that integrates optical, mechanical and electrical components. The machine has a novel shape, good reliability, operability and intuitiveness. It is a new type of Vickers and Knoop hardness testing instrument that uses precision mechanical technology and photoelectric technology. .
