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.

1 In low viscosity liquids, the read time should be set to the minimum allowed 1 minute to avoid free convection.

2 In dry granular materials where contact resistance can be significant, extending the read time to the maximum allowed 10 minutes will produce the most accurate results.

3 In solid materials where a pilot hole has been drilled and contact resistance can be significant, using thermal grease and extending the read time to the maximum allowed 10 minutes will produce the most accurate results.

4 The SH-1 sensor will take accurate measurements in rock and cured concrete, but it is very difficult to drill small small diameter, parallel holes in these materials to accommodate the SH-1 needles.

5 The KS-1 needle in default mode (Low Power, 1 min read time). Heater temperatures with the other probes are too high for insulation measurements.
