Ultra-High-Temperature Differential Thermal Analyzer

超高温差热分析仪

Phase diagram work on alloys, refractory oxides and molten salts can demand temperatures up to 2400 °C. This DTA combines a W-Re thermocouple with an optical pyrometer and holds argon or helium below 10 ppm O₂. Accuracy is ±5–10 °C at 2000 °C. Choose a graphite resistance or induction furnace, and graphite, tungsten or zirconia crucibles.

Temperature range: Ambient–2400 °C
Heating rate: 2–30 °C/min
Temperature accuracy: ±5–10 °C at 2000 °C
Temperature sensing: W-Re thermocouple and optical pyrometer
Atmosphere: Argon or helium, < 10 ppm O₂
