APNA–365 Ambient NOx Monitor High Sensitivity Type
Overview
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.
Features
- Ensure long–term stability according to dual cross–flow modulation method employment.
- To be realized 0–10ppb high sensitivity range.
