Guarded Hot Plate
Guarded Hot Plate is especially well-suited for thermal conductivity measurements at high temperatures, exhibiting unrivaled temperature and dimensional stability. Each of its components include state-of-art technology representing the best available today in advanced materials and electronics.
In a Guarded Hot Plate system a temperature difference (ΔT) is established across a sample of known thickness (L). The thermal conductivity is calculated from the temperature difference across the known thickness and the steady state power (W) per area (A) required to maintain the temperature difference. The Guarded Hot Plate uses a direct measurement of the electrical power supplied to the hot plate rather than heat flow meter signals from a Heat Flux Transducer.
