The three-tank thermal shock test chamber is used to assess the ability of products (complete machines), components, parts, etc. to withstand sudden changes in temperature. This temperature shock test can understand the impact of temperature changes on the test sample once or multiple times.The main parameters affecting the temperature change test are the high and low temperature values of the temperature change range, the holding time of the sample at high and low temperatures, and the number of cycles of the test.It is generally used in a wide range of fields, from research and development to inspection and production.

Automatic Focusing Vision Brinell Hardness Tester AuToBrin-3000Y is mainly used to measure the Brinell hardness of materials. The latest frame structure design, the high precision step-control system and the more intuitive measurement method are adopted. The structure is more stable, the control accuracy is higher, the time and effort are saved, and the accuracy is improved by an order of magnitude. The machine adopts electronic control automatic loading, computer software programming, high-power optical measurement, photoelectric sensor and other systems, and adopts high-precision step control technology to ensure that the load of test force does not overshoot. By manually fitting the indentation edge, the Brinell hardness is automatically calculated and displayed on the LCD screen. The reading is accurate and the operation is convenient.

Vickers method is based on an optical measurement system, it specifies a range of light loads using a diamond indenter to make an indentation which is measured and converted to a hardness value. It is very useful for testing on a wide type of materials, but test samples must be polished to enable measuring the size of the impressions. A square base pyramid shaped diamond is used for testing in the Vickers scale. Typically loads are very light, ranging from 5gf to 2Kgf, although "Macro" Vickers loads can range up to 50 Kg or more. Micro Vickers hardness methods are used to test on metals, ceramics, and composites - almost any type of material. Since the test indentation is very small in a Vickers test, it is useful for a variety of applications: testing very thin materials like foils or measuring the surface of a part, small parts or small areas, measuring individual microstructures, or measuring the depth of case hardening by sectioning a part and making a series of indentations to describe a profile of the
