Engine Emissions monitoring system (EEMS)

The Gasmet engine emissions monitoring system EEMS has been designed engine emissions monitoring which require for fast response time. A typical application for Gasmet EEMS consists of H₂O, CO₂, CO, N₂O, NO, NO₂, SO₂, HCl, HF, NH₃, CH₄, C₂H₆, C₃H₈, and C₂H₄, but it can be easily configured for a new set of compounds and/or calibration ranges.
