This instrument is a high-temperature, transmission projection device used for measuring the sintering point temperature and refractoriness of molding materials such as raw sand, mixtures, glass and ceramic raw materials. It enables the tester to clearly observe on the mirror screen the volume shrinkage, expansion purification and complete transformation of the material sample under high temperature conditions, as well as the corresponding temperatures at which various situations occur. It is widely used in the casting, ceramics, glass industries, as well as in teaching and research departments. This instrument complies with the requirements for instruments in the GBT7322-2017 standard for the test method of refractoriness of refractory materials.According to the user's requirements, a CCD camera and computer image processing system can be configured. All test operations can be completed through the computer interface. The operation is convenient, easy to learn and comes with a complete set of software.
