Heat Flow Meter Thermal Conductivity Analyzer

The instrument employs two symmetrically arranged heat flow meters, one at each plate, and supports automatic data collection, processing, report printing, and storage through a control PC. An embedded computer with a touch-screen interface is available as an option. The instrument references ASTM C518, ISO 8301, and GB/T 10295.

The automatic thickness measurement system covers 15–100 mm with incremental linear measurement and 0.1 mm display resolution, in accordance with EN 1946-3:1999. The specimen size is 300 × 300 mm, with a standard thickness of 10–50 mm and an optional thickened design up to 200 mm. Powder specimens can use a specimen cylinder or confining frame; the instrument provides a Ø90 mm rock-soil specimen cylinder. A motorized positioning system supports soft insulation materials and hard foams, with a 100 N specimen-positioning force.

The cold plate can be controlled at -30 °C, 0 °C, or 15.0 °C with 0.01 °C resolution. The hot plate is controlled from room temperature to 99.99 °C with 0.01 °C resolution, a flat-plate heater, bidirectional SCR control, and programmable PID data points greater than 10. Cooling options are forced air, an external water bath, or electronic cooling. The in-house heat-flow-meter calibration parameter is 23.26 W/m²·mV.
