Description
Summary:
Thermal shock climatic test chamber can be used in testing composite material and material
structure’s result which under continuous environment with high temperature or low temperature shock in short time; It means this product can test the material’s chemical change or physics change by expansion and contraction within short time. It’s application to metal, plastic, rubber, electronic etc materials and can be used for product improvement’s reference.
Applicable industries:
It applied to aviation, military, ships, electrical, electronics, instruments and meters; medical equipment; civilian nuclear energy; colleges and universities; research laboratories; commodity inspection, arbitration, and technical supervision departments; Building materials ceramic; petroleum
and chemical products, for high and low temperature impact test.
Standards:
