EN 12667 ASTM C518 ISO 8301 Thermal Conductivity Tester Heat Flow Meter Method
This thermal conductivity tester utilizes the heat flow meter method and complies with multiple international standards including EN 12667, ASTM C518, and ISO 8301.
Thermal Conductivity Tester (Heat Flow Meter Method)
- GB/T 10295-2008 - Thermal insulation - Determination of steady-state thermal resistance and related properties - Heat flow meter method
- GB/T 39704-2020 - Determination of effective thermal conductivity of vacuum insulation panels (VIP)
- EN 12667, ASTM C518, ISO 8301
Manufactured in accordance with GB/T 10295-2008 and GB/T 39704-2020 standards, this instrument is primarily used for measuring the thermal conductivity of STP and VIP vacuum insulation panels. It is widely applicable to thermal insulation material production enterprises, quality inspection departments, universities, and research institutes.
The instrument is designed for testing STP and VIP vacuum insulation panels, as well as various other thermal insulation materials including silicate insulation materials, ceramic insulation materials, XPS extruded boards, rigid polyurethane foam boards, foamed cement boards, EPS foam boards, perlite, vermiculite bricks, and similar materials.
This instrument employs a steady-state measurement method. Accurate results are obtained only after the cold plate and hot plate reach thermal equilibrium. According to the one-dimensional steady-state heat transfer equation, heat generated by the hot plate heater passes through the specimen to the cold plate and is then carried away by circulating water or other medium, forming a complete thermodynamic cycle.
- Integrated constant-temperature bath system
- Full computer control via user-friendly software interface
- Automatic data acquisition, processing, and calculation
- Real-time display and printout of thermal conductivity results
- Compact footprint, fast measurement, high accuracy, low noise
