Consequently， good reproducibility was obtained with RSD approximately 1.5%. TC of front and rear did not show any difference. -Measuring instrument- Main unit： QTM-500 Quick thermal meter Probe： PD-13 Insulating probe (1)Activated QTM-500 and left it over onehour. (2)Set the heater's current volume at|=6.3)Placed the prove on sample andmeasured TC of both sides， front andrear. Front Rear First： 4.907(W/m·K) 4.863(W/m·K) Second： 4.849 4.792 Third： 4.852 4.731 Fourth： 4.726 4.862 Fifth： 4.792 4.926 Mean： 4.825 4.835 sD： 0.069 0.075 RSD： 1.4(%) 1.6(%) -Ambient condition- Ambient： 24.9℃ Humidity：47 % Weather： Fine When probe is put on the sample， care should be taken for making close contact between sampleand probe.
