Elemental Instruments, a division of Ohio Lumex logo

Industrial Hygiene

Back in 1999, our one of our main reasons for starting Ohio Lumex was to assist the industrial hygienists and first responders with their mercury vapor detection needs by introducing a state-of-the-art RA-915 mercury analyzer to the market. The instrument become (and remains) an industry staple and must-have tool for the US EPA, hazmat offices, and fire departments across the nation.

Utilizing state of the art Zeeman background correction technology combined with a multi-pass cell enables our mercury instruments to make precise trace-level mercury measurements, even in the presence of interfering gasses.

In recent years, several instrument configuration improvements have been made based on the end user’s feedback. Our mercury analyzers have become smaller, lighter, quieter and more user friendly. We are constantly focused on innovation and take pride in our ability to continue providing our customers with the best available technology.

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