Kyoto Electronics Manufacturing Co.，Ltd.DataNo.HB00-07051 KEM Application Note No.TCL-07005Thermal conductivity measurement Thermal conductivity(TC) of refractory brick -Summary- The purpose of this measurement is to check reproducibility of the equipment. For this，checked reproducibility with several kinds of brick， and good results was obtained withinequipment specification. -Measuring instrument- Main unit： QTM-500 Quick thermal meterProbe： PD-11 (1) QTM was left activated for one hour untilprobe and sample were reached the set degree. Measurement： (1) Made close contact between prove faceand sample and set the heater’s currentvolume， and measured TC.
