2B Technologies NO2 Converter  

Definition

  • The Model 401 NO2 Converter (above photo, right), when used in combination with the Model 410 Nitric Oxide Monitor, (above photo, left) allows measurements of NO, NOx (NOx = NO + NO2) and NO2 (as the difference between NOx and NO) in the range 0-2,000 ppb. The NO2 Converter also contains an internal scrubber for scheduled zeroing of the NO Monitor. The NO2 Converter makes use of a molybdenum ("moly") converter heated to 325 °C to reduce NO2 to NO. Frequencies of switching between NO and NOx measurements and zeroing frequencies are chosen from the NO Monitor menu. The instrument package may be set to either always measure NO, always measure NOx, or switch back and forth between measurements of NO and NOx at a specified interval (5 min, 15 min or 1 hour). Choices of zeroing frequency are never, continuous, and at 30 min, 1 hour and 4 hour frequencies. Menu choices of NO/NOx and zero measurement frequencies can be customized to your needs. (en)
