Portable Chlorine Gas Detectors

Chlorine gas detectors measure Cl2 concentration in air. Check the individual instrument's stated sample requirements. Compare dedicated chlorine 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 Cl2 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.
