Fully Automatic Thermal Conductivity Equipment Protective Plate Heat Flow Meter Method
LRPL-III-300 Fully Automatic Thermal Conductivity Equipment (Protective Plate Heat Flow Meter Method)
1.Description:
This instrument adopts the internationally popular method of using thermal flow meters to measure the thermal conductivity and thermal resistance. It is equipped with a computer to achieve fully automatic testing and generate experimental reports. It is suitable for testing the thermal properties of low thermal conductivity materials such as insulation materials and refractory materials. With the addition of a sample frame, it can also be used for powder material testing. It is widely used in universities, research institutes, quality inspection departments, factories and mines.
2.Standard
The methods for determining the thermal resistance and thermal conductivity of JIS-1412-2 heat-resistant materials, GB/T10295-2008, ISO 8301:1991 (the steady-state thermal resistance and related properties of insulation materials - the hot flow meter method), and ASTM C518-04 (the test methods for determining steady-state heat flux and heat transfer characteristics using the hot flow meter method).
