Nitrogen dioxide detectors measure NO2 concentration. Nitric oxide uses a separate gas channel. Compare dedicated nitrogen dioxide instruments by concentration range, reading increment and sampling arrangement. Internal pumps, diffusion sampling and optional external-pump packages depend on the exact model.

Select the NO2 configuration and range shown on the product page before ordering. Review sensor maintenance, calibration and sample-line requirements for the intended measurement. For a configurable instrument family, browse our single-gas detector options. To compare other gases or multi-gas instruments, return to all gas detectors and monitors.
