Hot-Wire Method Thermal Conductivity Analyzer

The DRX-I-RX thermal conductivity analyzer uses the hot-wire method to measure the thermal conductivity of refractory insulation products and granular or powdered materials. It supports both cross and parallel measurement configurations in a single instrument, with automated testing controlled by computer. Measurement ranges: cross method 0.015–1.7 W/m·K; parallel method 0.015–20 W/m·K. Accuracy is ±5%. Maximum operating temperatures are 1000 ℃, 1400 ℃, and 1600 ℃. The maximum specimen size is 230 × 114 × 65 mm. The metering heating power is adjustable and can be computer-controlled. The instrument enables testing by both cross and parallel methods, providing full automation via a computer interface. It is designed for reliable determination of thermal conductivity in non-metallic solid materials and insulating refractories. Reference standards include: GB 5990-86 (Thermal Conductivity Test Method for Shaped Insulating Refractory Products, hot-wire method), GB/T 10297-1998 (Determination of Thermal Conductivity of Non-metallic Solid Materials, hot-wire method), and GB/T 17106-1997 (Thermal Conductivity Test Method for Refractory Materials, parallel method). The integrated design combines cross and parallel testing to deliver efficient, consistent measurements.
