| SAMPLE SIZE | Sample size is dependent on the thermal properties of the material being tested. In general a 2cm radius of sample material around the needle(s) is sufficient for samples with thermal conductivities around 0.5 W/mK. Samples with lower conductivity (i.e. insulation) can be tested with a smaller sample size. Samples with a higher conductivity (i.e. granite) will require a larger sample to avoid boundary effects. | |||
The large (10cm long, 2.4mm diameter) single needle TR-1 sensor measures thermal conductivity and thermal resistivity (part number 40352). The TR-1 was designed for us in soil, concrete and other granular or solid materials. If measuring cured concrete (or any other material that requires drilling…
The 6cm long, 3.9mm diameter single needle RK-1 sensor measures thermal conductivity and thermal resistivity (part number 40351). The RK-1 was designed for us in rock, concrete and other solid materials that require the drilling of a pilot hole. The RK-1 sensor should not be used in liquids. See…
The small 6cm long, 1.3mm diameter single needle KS-1 sensor (part number 40354) measures thermal conductivity and thermal resistivity of liquids and insulating materials. See the sensor comparisons tab on the KD2 Pro page for a side-by-side comparison of the sensors. Contact us…
The dual needle SH-1 sensor (3cm long, 1.3mm diameter, 6mm spacing) measures volumetric heat capacity, thermal diffusivity, thermal conductivity, and thermal resistivity (part number 40353). The SH-1 is compatible with most solid and granular materials. The SH-1 sensor should not be used in…
