惰性气体熔融氧氮氢分析仪
Titanium and zirconium producers watching hydrogen, steelmakers controlling oxygen and nitrogen, and copper refiners checking oxygen will find the ranges they need here. Furnace power up to 8 kW melts 0.1–1.0 g at roughly 2000–3000 °C. Hydrogen reads from 0.05 ppm, oxygen from 0.1 ppm to 5 %; each run takes 60–150 s.
