Gasmet DX4000 is a portable FTIR gas analyzer for applications where multiple gas compounds need to be accurately monitored in hot & humid sample gas. It is the world’s smallest FTIR emissions monitoring system, and typically set up to measure H₂O, CO₂, CO, NO, NO₂, N₂O, SO₂, NH3, CH4, HCl, HF and different VOCs. The system can measure up to 50 gases simultaneously. Additional gases can be easily added without any hardware changes. The DX4000 is used in combination with our Portable Sampling System (PSS).
