DRE-2E Thermal Conductivity Tester (transient hot wire method)

The DRE-2E instrument uses a cross hot wire (or cross wire) sensor for measuring powder and solid bulk materials. Weld a temperature thermocouple in the middle of the heating wire to measure the temperature of the hot wire. This hot wire has a much thicker diameter than a single hot wire and is not easily broken, so it can be used to measure powders, solid bulk materials, and can be measured at relatively high temperatures. But the hotline is bare wire, and conductive materials cannot be directly detected.
