Key Features
Adaptable to Any Sample Size
With three flexible configurations—Small, Medium, and Large—the HFM 706 Lambda Series is perfectly designed for your unique sample dimensions. Whether you’re analyzing small laboratory specimens or substantial industrial materials, our models consistently deliver precise and dependable results.
The HFM 706 Lambda Small is an excellent fit for samples up to 203 mm x 203 mm, with a maximum height of 51 mm.
For larger samples, the Medium and Large versions provide ample space, ensuring versatility across various applications.
High-Sensitivity Transducers for Accurate Thermal Analysis The HFM 706 Lambda Series is equipped with dual heat flux transducers that vigilantly monitor heat flow. These transducers offer exceptional sensitivity and accuracy. Our advanced calibration method incorporates reference materials with established thermal conductivity, and by integrating multiple calibration techniques, we guarantee superior measurement precision. This approach consistently yields reliable and reproducible data.
Faster Results and Enhanced Performance with Modern Peltier Technology Experience meticulous temperature management with our sophisticated Peltier temperature control system for both hot and cold plates. Robust, bidirectional Peltier elements, coupled with an external chiller, ensure rapid and precise heating and cooling of each plate. This optimized temperature control quickly achieves thermal equilibrium, providing consistent, dependable data in less time, thereby boosting your laboratory’s productivity and efficiency.
Optimized Test Chamber Design for Reliable Results and Minimal Condensation Our innovative test chamber is engineered to minimize environmental interference and significantly reduce condensation within the chamber and on the plate surfaces. For even finer control, an optional dry gas purge feature helps maintain optimal humidity levels, establishing consistent test conditions and further enhancing measurement reliability.
Beyond Thermal Conductivity: Analyzing Specific Heat Capacity (c p)
The HFM 706 Lambda’s integrated hardware and software can also determine your samples’ specific heat capacity (cp), providing a comprehensive thermal profile. This dual functionality expands the versatility of your measurements, offering deeper insights into material properties for both research and quality control.
