Sky with smog

For 25 years Ohio Lumex has provided precise mercury vapor analyzers for indoor and outdoor air quality measurements. Our analyzers are cited in many US EPA manuals as an industry standard, and are recognized as the go-to measurement devices for first responders as well as occupational and environmental health and safety professionals. Utilizing state of the art Zeeman background correction technology combined with a multi-pass cell enables our instruments to make precise trace-level mercury measurements, even in the presence of interfering gasses.

Please contact us if you have any questions about the available options and customizations.
