Figure 1: The NETZSCH heat flow meter is a fast and easy-to-use instrument for accurately measuring the low thermal conductivity, λ, of insulation materials |
In the world of thermal insulation, precision and reliability are key to accurately measure thermal conductivity (Thermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature). That’s why NETZSCH has redefined heat flow measurements with the new NETZSCHHFM 706 Lambda series, available in three sizes to accommodate a wide range of specimen dimensions, from small laboratory samples to large industrial materials.
Whether you’re working with classic insulation materials like stone or glass wool, polymer foams or advanced systems such as vacuum insulation panels (VIPs), the new HFM 706 instruments allow for accurate measurements of thermal conductivity over a temperature range of -30°C to 90°C – quickly, easily, and based on global standards such as ASTM C518, ISO 8301 and EN 12667.

Figure 2: The HFM 706 Lambda is available in three sizes. Choose from among: Small 203 mm x 203 mm x up to 51 mm, Medium 305 mm x 305 mm x up to 105 mm, Large 611 mm x 611 mm x up to 200 mm |
Designed for Maximum Efficiency
From its intuitive SmartMode software to automated thickness determination using a high-resolution transducer, every aspect of the HFM 706 is optimized for ease of use and reproducibility.
Features such as fast sample exchange and programmable plate positioning help minimize heat loss during handling and reduce overall measurement time.
The three instrument sizes (Small, Medium, Large) allow for unmatched versatility, while a rear-door option on the large version enables the measurement of oversized panels — without damaging delicate structures like VIPs.
