-
Simultaneous measurements for two components among NOx, SO2, and NH3
Less interenference from moisture and particles as it uses UV light source
NOx converter is not required as it measures NO and NO2 separately
Enclosure level up to IP66 and NEMA4X
Real Gas Calibration using patented Auto Calibration Unit (ACU)
EX version is available as an option
