Handheld Thermal Conductivity Meter TLS-100
Handheld Thermal Conductivity Meter TLS-100
Product details
-
The transient thermal conductivity meter utilizes the Transient Line Source technique (TLS technology), which involves heating a metal heating wire with a fixed current to measure temperature changes. The Resistance Temperature Detector (RTD) measures the temperature and impedance characteristics of the metal, allowing a portion of the heat to be conducted away by the sample and another portion to be carried around the heating wire. The thermal conductivity and thermal resistance are calculated based on changes in the electrical resistance of the heating wire.
