Summary:A fine needle probe for determining the thermal conductivity of penetrable materials such as fluids, fruit and animal flesh has been developed. The probe is constructed by inserting 20 strands of copper wire with electrical insulation coating into a fine stainless steel needle. It has been found that the effects of the thin needle wall can be negligibly small if the instruments and the measurement procedure are adequately designed. The accuracy of measurements is estimated to be within +or-3%. (Original abstract - amended)
