The instrument is used to measure the thermal conductivity and heat capacity of various refractories. The equipment is manufactured in accordance with GB / T 5990 test method for thermal conductivity (hot wire method) (equivalent to iso8894 test methods for thermal conductivity of refractories Part 1: cross hot wire method and iso8894 test method for thermal conductivity of refractories Part 2: parallel hot wire method). IPC industrial computer is used for automatic control, with high-precision acquisition board and special software to realize temperature control and accurate measurement of thermal conductivity. The heating rate can be set arbitrarily within a certain range. The interface is friendly. The dynamic real-time display of temperature time curve, hot line temperature time curve and relevant parameters of monitoring are displayed. The original data can be converted into excel storage format and can be read at any time Query and print the test report with thermal conductivity curve.
