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 with 10 min read time gives good results with insulation. Heater temperatures with the other two probes are quite high for insulation measurements.
