آنالایزر in-situ - آزمایشگاه کالیبراسیون دقیق تجهیز

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
