Guarded Hot Plate vs. Heat Flow Meter: Key Differences

Описание: Welcome to another episode of the Thermtest Educational Series! In this video, we compare two of the most widely used steady-state thermal conductivity methods — the Guarded Hot Plate (GHP) and the Heat Flow Meter (HFM).

Although both methods rely on the same steady-state principles, they differ significantly in how heat flow is measured, and those differences affect accuracy, speed, sample preparation, and testing applications.

Whether you need high-precision certification or fast, repeatable QA data, understanding the difference between GHP and HFM ensures you choose the right method for your material and your goals.
