DRPL-III high precision material thermal conductivity tester
Introduction: It adopts the internationally popular heat flow meter to detect thermal conductivity and thermal resistance, and it is equipped with a computer to realize automatic detection and generate experimental reports. The instrument uses a stable hot surface temperature on one side of the sample, heat is transferred to the cold surface through the sample, and the transferred heat flow is measured to calculate the thermal conductivity and thermal resistance. Using imported sensors and computer technology, it has the characteristics of good measurement accuracy, high reliability and good repeatability. Especially suitable for the measurement of low thermal conductivity (accurate to 0.1mw). It can be used for testing of plastics, rubber, insulation materials, etc., and is widely used in universities, colleges, research institutes, quality inspection, factories and mines. Reference standard: GB/T10295-2008 (Thermometer method for the determination of steady-state thermal resistance and related characteristics of thermal insulation materials) and ASTM C518-04 Test method for measuring steady-state heat flux and heat transfer characteristics by the heat flowmeter method. Features: 1. The sample is accurately clamped by computer, the pressure range is 0-1000N, and the resolution is 0.1N. 2. Automatic measurement of sample thickness, 0-50mm, resolution 1um. 3. Adopt imported heat flow meter, stable and reliable performance. 4. The whole process adopts computer automatic test and storage, printing and storage of experimental data technical parameters: Can test solid materials and powdered materials. Technical parameter: Range and accuracy of thermal conductivity: 0.0001～3W/mk, can be measured accurately to 0.1mw/mk. 0.001～300W/mk Measurement accuracy: 1%. Sample size: 50×50～300×300 (mm). Special size can be customized. Measuring time: 15-20min. Hot surface temperature and control: room temperature-199.9°C (standard configuration), room temperature-499.9°C, higher temperature can be determined according to user requirements. Plate heater, bidirectional thyristor control, temperature control accuracy 0.1℃. Cold noodle temperature and control: 0-99.9°C (standard configuration), -10-99.9°C, lower temperature can be determined according to user requirements. The cold noodle is water-cooled to ensure the stable temperature of the cold noodle (precision constant temperature water tank, temperature adjustable), and the temperature control accuracy is 0.1℃. .
