- Commodity name: Refractory Material Hot Wire Thermal Conductivity Tester
- Model: DRX-3
The refractory materials hot wire method thermal conductivity tester mainly measures the thermal conductivity, thermal diffusivity, and specific heat capacity of solid and powder materials at different temperatures. It features high precision, high resolution, and high reproducibility. It is automatically measured by computer control.
Refractory Material Thermal Conductivity Tester (Hot Wire Method)
Xiangtan Xiangke DRX-3 (Hot Wire Method) Thermal Conductivity Tester
I. Overview
The DRX-3 thermal conductivity tester uses the transient hot wire method, including the cross-wire method and the parallel-wire method, mainly to measure the thermal conductivity, thermal diffusivity, and specific heat capacity of solid and powder materials at different temperatures. It features high precision, high resolution, and high reproducibility. It is automatically measured by computer control. It is widely used in research institutes, quality inspection, factories and mines, etc., for the measurement of material thermal conductivity.
This instrument is newly developed and designed based on our original DRX-2, improving the measurement accuracy and reproducibility, making the structure more reasonable and easier to use. Model classification: DRX-3A mainly uses the cross-wire method (the parallel-wire method can also be used to measure materials below 5w/mk); DRX-3B uses the parallel-wire method to measure materials less than 25w/mk.
Instrument reference standards: GB/T 5990-2021 "Refractory materials Test methods for thermal conductivity, specific heat capacity and thermal diffusivity (hot wire method)"; GB/T 17106-1997 "Test method for thermal conductivity of refractory materials (parallel wire method)"; GB/T 11205-2009 "Determination of thermal conductivity of rubber (transient hot wire method)"; GB/T10297-2015 "Determination of thermal conductivity of non-metallic solid materials (hot wire method)", etc.
II. Refractory Material Thermal Conductivity Tester (Hot Wire Method) Main Technical Indicators
1. Measurement range: DRX-3A (cross-wire method) 0.015~2.0 W/(m·K)
DRX-3A (parallel-wire method) 0.015~5.0 W/(m·K)
DRX-3B (parallel-wire method) 0.015~25.0 W/(m·K)
2. Temperature range: Routine testing is at room temperature. Different constant temperature devices and test hot wires can be selected according to user requirements for testing at different temperatures. The cost will be calculated separately, as follows:
-40～120 ℃ (high and low temperature constant temperature box required) with copper-constantan hot wire
Room temperature～1000 ℃ (resistance wire resistance furnace required) with nickel-chromium-nickel-silicon or platinum-platinum rhodium hot wire
Room temperature～1300 ℃ (silicon carbide rod resistance furnace required) with platinum-platinum rhodium hot wire
Room temperature～1600 ℃ (silicon molybdenum rod resistance furnace required) with platinum-platinum rhodium hot wire
3. Measurement accuracy: <±5.0 %
4. Sample size: 2 pieces of rectangular parallelepipeds no less than 40mm×80mm×114mm that are symmetrical to each other, or 2 pieces of semicylinders with a cross-sectional diameter no less than 80mm and a length no less than 114mm combined into a cylinder; (or customized according to user requirements),
5. Temperature resolution: 0.001℃
6. Hot wire power supply: DRX-3A current resolution 0.01mA, voltage resolution 0.1mV
DRX-3B current resolution 0.1mA, voltage resolution 0.1mV
7. Equipment power supply: Voltage 220V; frequency 50Hz; power 500W (refer to the electric furnace temperature controller manual for the power supply requirements of the electric furnace temperature controller)
