Musktool-QTM-700-710-Rapid_Thermal_Conductivity_Meter
Product Overview
The hot wire method is a transient method for measuring the thermal conductivity of materials. Its principle is to place a resistance wire, the so-called "hot wire", in a homogeneous, isotropic sample at a uniform temperature. When the hot wire releases heat at a constant power, the temperature of the hot wire and the sample in its vicinity will rise over time. The thermal conductivity of the sample can be determined based on the relationship between its temperature and time. Thermal conductivity: Under heat transfer conditions, it represents the amount of heat transferred per unit area per unit time when the temperature difference between two planes separated by a unit length is one unit (K). The unit is W/(m·K). |
Product Feature
1. Featuring a 5.7-inch color touchscreen for intuitive display and user-friendly operation. 2. The sensor supports simultaneous connection of three channels, enabling faster sample testing. 3. Security levels and password protection settings effectively prevent accidental operations. 4. Measurement data can be transferred via USB drive and automatically converted to CSV format. 5. Standard thermal conductivity reference plate is included to ensure measurement reliability. 6. The measurement time is short (60 seconds) and the measurement range is wide (0.03~12 W/mK). 7. Automatic setting of heating current, real-time temperature rise curve, and repeatable measurement. 8. The QTM-710 features thin-film sample measurement capability and comes with three standard reference plates. |
