Oxygen detectors measure O2 concentration, usually expressed as a volume fraction on the selected model. Compare dedicated oxygen 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 O2 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.
