Measure the diffusivity and heat capacity of solid materials

The dimensions of the TR-4 sensor conform to the specifications for the Lab Probe called out by the IEEE 442-1981, Guide for Soil Thermal Resistivity Measurements; the IEEE 442/D3, Draft Guide for Thermal Resistivity Measurements of Soils and Backfill Materials; and, ASTM D5334, Standard Test Method for Determination of Thermal Conductivity of Soiled and Soft Rock by Thermal Needle Probe Procedure. We recommend using an appropriately sized drill bit for measuring very hard materials like concrete or rock.
