DRH300 Heat Flow Meter (HFM)

DRH300 is a heat flow meter (HFM) for determining thermal conductivity and thermal resistance of insulation boards and other solid materials, using one heat-flow sensor on each plate. It covers 0.005–2.0 W/(m·K) thermal conductivity and 0.1–8.0 m²·K/W thermal resistance, with computer-controlled testing and reference to ASTM C518, ISO 8301, and GB/T 10295.

Product Description

The DRH300 uses the heat flow meter method with dual heat-flow sensors, one on each plate. It supports insulation boards, clay, sand, ceramics, and plastics, with automated temperature control, data acquisition, processing, report generation, printing, and storage.

The specified specimen size is 300 × 300 mm, with thickness of 10–50 mm. The hot plate is rated to 100 °C, and the cold plate reaches a minimum of −30.0 °C. Hot-surface temperature control covers ambient temperature to 99.99 °C with more than 10 programmable points; cooling options are forced-air cooling, an external water bath, or thermoelectric cooling.

Automated testing is computer controlled, and an embedded touchscreen computer is optional.

Ordering information: Specify specimen size and thickness, custom test-temperature range, the selected cooling method, and control-computer configuration when requesting a quotation.
