The DEFOR is an extractive UV gas analyzer for simultaneous measurement of up to three components. It is a specialist for extremely selective NO-measurements of small ranges. It is a generalist for many UV-active gases like SO2, NO2, Cl2, NH3, CS2, H2S and COS. It shows no cross-sensitivities to CO2 and H2O due to the used spectral range. The innovative signal processing as well as the highly stable detectors provide an outstandingly longterm stability and allow the compensation of drifts and other effects. The state-of-the-art electronics and software provide the required interfaces for remote control via networks and integration into process control systems. |
