DRX-I-SPB Thermal Conductivity Testing Machine ASTM C417for Refractories The tester is mainly used to test low thermal conductivity of refractory materials, refractory ceramic fiber products, heat insulating brick and board, and thermal conductivity of fire-resistant materials and powdery materials. It achieves automatic control by applying industrial PC, with friendly interface, high precise temperature control, and printing test report automatically. The instrument is based on the principle of heat shield plate method, and is equipped with relevant national standard requirements, and made the corresponding improvement, the test work is completed automatically by the computer, and the digital display of each state point. The test can also be completed manually, meeting the high-precision test requirements of thermal conductivity of materials for material inspection and research department.
