DRH-30S Heat Flow Meter (HFM)
The DRH-30S measures thermal conductivity and thermal resistance of homogeneous board materials by the heat-flow method, with automatic pressure and thickness measurement. It is described for low- and high-conductivity materials, including plastics, rubber, glass, fibers, foams, concrete, ceramics, rock, soil, refractories, and insulation materials.

Product Description
The specimen is tested between a hot plate and cold plate with selectable pressure, multilayer measurement for thin films, an imported heat-flow sensor, and automatic thickness measurement.
Independent operation and control-computer operation are available; the applicable control-computer configuration requires confirmation.
Ordering information: Specify the selected method, measurement range, high-conductivity configuration, and control-computer requirements when requesting a quotation.
