DRPL-III Thermal Conductivity Tester for Insulation Materials (Protective Plate Heat Flow Meter Method)

This instrument uses internationally popular heat flow meters to detect thermal conductivity and thermal resistance, and is equipped with a computer to achieve fully automatic detection and generate experimental reports. Suitable for testing the thermal conductivity of low thermal conductivity materials such as insulation materials and refractory materials. With the addition of sample frames, it can be used for powder material testing and is widely used in colleges, research institutes, quality inspection, factories and mines.

Standards：GB/T10295-2008 (Determination of steady-state thermal resistance and related characteristics of insulation materials using a heat flux meter method) and ASTM C518-04 (Test method for determining steady-state heat flux and heat transfer characteristics using a heat flux meter method).
