DGA-X
Brand:DXG
Origin:Korean
Overview
UV Absorption – NOx, SO₂, NH₃
- Measures in the low wavelength UV range (200 ~ 400 nm) for high precision and minimal moisture interference
- Utilizes the differential optical absorption spectroscopy (DOAS) method, eliminating the need for calibration
- Selectively measures two gases out of NOx, SO₂,and NH₃ simultaneously
- Enables individual NO and NO₂ measurements without the need for a NOx converter
- Optional addition of a standard gas calibration device
