42iQ is an analyzer that measures nitric oxide (NO), nitrogen dioxide (NO₂) and total nitrogen oxides (NOₓ) by the chemiluminescence method. NO in the sample reacts with ozone and emits light; the intensity of the emitted light is proportional to the NO concentration. NO₂ is reduced to NO through a converter and measured as NOₓ.

The instrument is used at air quality monitoring stations, in process and emission measurements and in calibration laboratories. The family also includes the 42iQHL (High Level) configuration for high concentration ranges.

42iQ features

  • Simultaneous measurement of NO, NO₂ and NOₓ by chemiluminescence
  • Molybdenum converter option; options such as ammonia scrubber and stainless steel converter
  • Automatic calibration check with internal zero/span assembly
  • Connection to data acquisition systems through serial RS232/RS485
  • Measurement ranges from 0-10 ppm to 0-5,000 ppm with the high-level (HL) version
  • Renewed iQ series platform; 220-240 VAC 50/60 Hz supply
