Dispositivo de conductividad térmica DRE-2A
Introducción
This series of thermal conductivity meter adopts the unsteady state method, which has the advantages of fast measurement speed, wide application range and the ability to successfully avoid the influence of natural convection in the experiment process. It is a popular test method at present.
DRE-2A thermal conductivity tester adopts transient hot wire method, mainly measures the thermal conductivity of liquid. It has the characteristics of fast measurement speed, small sample quantity, alta precisión, high resolution and high reproducibility. Automatic measurement by computer control. Widely used in petroleum, químico, biológico, farmacéutico, energía, power engineering and other fields of working fluid thermal conductivity measurement.
