KP8104 double plate thermal conductivity apparatus
1, scope of application:
Applies: clay, sand dry specimen coefficient of thermal conductivity, thermal resistance of the sample should be greater than 0.1 m2. The K/W.
Using heat flow meter test of clay, sand, etc. The coefficient of thermal conductivity and thermal resistance method, even the computer to realize automatic detection and generate test report. Instrument used in the sample side join stable heat surface temperature, heat through the specimen is passed to the grim (room temperature), the measurement of transmission of heat flow to calculate the coefficient of thermal conductivity and thermal resistance. Designed with rock and soil sample tube and heat capacity test device, can make the soil such as clay, sand and specific heat capacity and thermal analysis. Electronic circuits, computer use special procedures for measurement and control. Pt100 temperature sensor, import electronic devices with high precision and high precision circuit, data acquisition card and computer measurement and control. Automatic data acquisition, data processing, report printing and data storage.
Second, conform to the standard:
