Namibia High-Temperature Thermal Conductivity Tester (Guarded Hot Plate Method)
Product Description
Xiangtan Xiangke DRS Series High-Temperature Thermal Conductivity Tester (Guarded Hot Plate Method)
I. Overview
This instrument is developed based on our factory's DRS-2 water flow plate method thermal conductivity tester. Compared with DRS-2, it improves resolution and automation, shortens testing time, is easier to maintain, and has more reliable performance. This instrument is suitable for testing the thermal conductivity of refractory insulation, ceramic fiber, felt, textiles, plates, and bricks at different temperatures. It is widely used in colleges and universities, research institutions, quality inspection departments, and material analysis and testing in manufacturing plants.
This instrument refers to the following standards: ASTM C518-04 Test Method for Determining Steady-State Thermal Flux and Thermal Transmission Properties by Means of a Heat Flow Meter; GB/T 10295-2008 Determination of Steady-State Thermal Resistance and Related Properties of Thermal Insulation Materials (Heat Flow Meter Method); YB/T 4130-2005 Refractory Materials Thermal Conductivity Test Method (Water Flow Plate Method); GB/T 17911-2018 Refractory Ceramic Fiber Products Thermal Conductivity Test Method, etc.
II. Xiangtan Xiangke DRS Series High-Temperature Thermal Conductivity Tester (Guarded Hot Plate Method) Main Technical Parameters
The DRS series instruments are mainly used for the thermal conductivity detection of thermal insulation materials at high temperatures. DRS-3B has a vacuum atmosphere protection function to prevent sample oxidation.

Both DRS-4 and DRS-4A are electrically pressurized and automatically measure thickness. The difference is that the DRS-4 hot plate uses heat-resistant stainless steel, with a slightly lower operating temperature, while the DRS-4A hot plate uses silicon carbide, with slightly lower pressure resistance, and the thickness measurement requires an additional thickness correction system, but the hot surface operating temperature is higher.
