Nitric Oxide Monitor [410]

The Model 410 Nitric Oxide Monitor™ is designed for the measurement of atmospheric nitric oxide (NO) in the concentrtion range 0-2,000 ppb (0-2 ppm) with a precison of ±1.5 ppb.  The detection principle of the Model 410 is based on the selective reaction of NO with ozone. The resulting ozone depletion is measured using the absolute method of UV absorbance and thus requires only infrequent calibration. By comparison, chemiluminescence NOx instruments require nearly continuous calibration using a standard gas.

See our Model 405 nm NO/NO2/NOx Monitor for simultaneous measurement of NO, NO2, and NOx.
