Elemental Instruments, a division of Ohio Lumex logo


Founded in 1999

Ohio Lumex was founded in 1999 and quickly made its mark with a new, highly accurate technology to measure mercury in ambient air that became the standard for the US EPA. Since then, we have expanded and taken leadership positions in analysis of combustion gas emissions, biogas and Renewable Natural Gas (RNG), and continue to expand our offering of products and services to be able to better support the needs of our customers.

Our sustained focus on research and development, drive to innovate, commitment to quality, and dedication to supporting our customers has allowed us to become a recognized leader in the field of gas analysis. We look forward to continuing to provide our customers with big results while still maintaining our small company feel and entrepreneurial spirit.
