To study the insulating performance of the thin thermal insulating material. A testing system has been developed with LabVIEW for measurements of thermal conductivity on building thermally insulating materials. The thermally insulating coating＇s thermal conductivity measuring system based on virtual instrument was discussed. This instrument has the ability of on-line analysis and evaluating materials＇ thermally conductivity. And it can be controlled by mcu 89c2051 one wire temperature sensor ds18b20 and so on. It gives the designed method and controlled flowchart of testing the thermal conductivity by LabVIEW.
