The measuring device increasment by cooling method. For those uneven quality of soil characteristics, in the amount of sampling on fully considered the representative. In the sample center can be measured accurately, insert thermocouple sample of heat transfer process, and the temperature numerical comparison, can judge thermocouple temperature after heat transfer to balance. The device adopts the high accuracy of measurement temperature highlighted.it thermocouple and watch, to ensure the accuracy of measurement.
The experiment equipment
