APNA–365 Ambient NOX monitor – High sensitivity type employs dual cross–flow modulation method based on Chemiluminescence method, which ensure long–term stability along with selectivity advancement of NO, NO2 and NOx (NO+NO2). It enables continuous measurement with 0.1ppb at lower detectable sensitivity.
