DRPL-VIII high-precision material thermal conductivity tester Introduction: Adopting the internationally popular method of using a heat flux meter to measure thermal conductivity and resistance, coupled with a computer to achieve fully automatic detection and generate experimental reports. The instrument uses a stable hot surface temperature added to one side of the sample, and heat is transferred to the cold surface through the sample. The heat transfer is measured to calculate the thermal conductivity and thermal resistance. Adopting imported sensors and computer technology, it has the characteristics of good measurement accuracy, high reliability, and good repeatability. Especially suitable for measuring low thermal conductivity (accurate to 0.1mW). It can be used for testing plastics, rubber, thermal insulation materials, aerogel plates, vacuum glass, etc., and is widely used in colleges, research institutes, quality inspection, factories and mines. Reference standards: GB/T10295-2008 (Determination of Steady State Thermal Resistance and Related Characteristics of Thermal Insulation Materials by Heat Flow Meter Method) and ASTM E1530, ASTM C518-04 Test Method for Determining Steady State Heat Flux and Heat Transfer Characteristics by Heat Flow Meter Method.
