DRX-I-300C Thermal-Properties Tester
The DRX-I-300C measures thermal properties of disturbed clay, sand, and similar soils, as well as solid powdered materials, with added methods for specific heat capacity and thermal conductivity. It is intended for construction engineering and soil-geology research under GB/T 50123-1999, with an optional freezing chamber for frozen-soil testing.

Product Description
The DRX-I-300C measures the thermal properties of disturbed clay, sand, and similar soils and supports research on heat transfer in solid powdered materials. It uses a control computer for data acquisition, automated analysis, data storage, and report output, and adds specific-heat-capacity and thermal-conductivity methods to the GB/T 50123-1999 soil-test method. A freezing test chamber can be added for frozen-soil thermal-conductivity analysis.
The system comprises a temperature-control system, temperature-measurement system, specimen box, and computer test system. Two thermostatic baths provide separate circulating temperatures to the specimen box; platinum-resistance thermometers feed the data-acquisition system, and a DC heat source maintains constant power.
