2BTech-405 NO2

2BTech-405 NO2/NOx/NO Monitor

The Model 405 nm NO2/NO/NOx Monitor™ measures NO2 directly by absorbance at 405 nm using a miniature White cell. Nitric oxide (NO) is measured by modulating the addition of ozone to quantitatively convert NO to NO2. This new instrumental approach has the advantages over chemiluminescence of being an absolute method and of requiring much less power, enabling portable measurements of NO2, NO and NOx.

Principle of Measurement Direct absorbance of NO2 at 405 nm
Measurement Modes NO2 only; NO only; NO2, NO and NOx
Linear Dynamic Range 0-10,000 ppb (0-10 ppm) for NO2; 0-2,000 ppb (0-2 ppm) for NO and NOx
