Combustion method with HF induction furnace and infrared detection

Fully programmable furnace power,  ceramic HF tube (3.5 kW @ 20 MHz), plate & grid current monitoring

High-end NDIR detection system and data processing enables quantification from sub ppm to high percent levels

Automatic furnace cleaning system

Easy to operate but powerful Win7 based software

Optimized flow design with multiple Oxygen supplies to achieve shortest analysis times (≤ 40 s; 20-30 s typical)

Lance flow with soft-start functionality to avoid blowing away light sample particles
