About Ohio Lumex
Ohio Lumex Co., Inc. is a Northeast Ohio analytical technology company that measures difficult analytes, above all mercury, at trace levels. Founded in 1999, when it introduced the RA-915 Zeeman mercury analyzer to the US market, it now combines instruments, sorbent traps, an accredited laboratory and field testing under one roof.
Headquartered in Solon, Ohio, the company serves electric utilities, cement plants, incinerators, gas producers and research labs across North America. In February 2026 it launched an Integrated Technology Solutions (ITS) division in Valparaiso, Indiana, for PLC/SCADA integration, control panels and commissioning.
What Ohio Lumex makes
Mercury measurement remains the core of the business. For stacks and process gas, the 915J continuous mercury monitor is built for coal-fired boilers, cement kilns and incinerators. Portable RA-915M analyzers handle spill response and exposure checks, and laboratory systems such as the M324 analyze sorbent traps with minimal sample preparation.
The Elemental Instruments brand, launched in 2020, extends the company into gas quality. The Ei800 process GC and Ei2200 RNG monitoring system report composition, heating value and siloxanes for renewable natural gas and biogas projects, while the Ei4200 measures actual acid dew point rather than estimating it. Ohio Lumex is also the exclusive North American distributor for G.A.S. GC-IMS instruments and distributes PyroScience optical oxygen, pH and temperature sensors in the US and Canada.
Why engineers specify Ohio Lumex
- One accountable source. A plant can buy the monitor, the Method 30B traps, third-party lab analysis and RATA field support from the same company.
- Proven measurement physics. Zeeman atomic absorption with a multi-pass cell reads mercury directly, even with SO2, moisture or organics present.
- Accredited laboratory. The lab holds ISO/IEC 17025:2017 accreditation through A2LA and NELAP accreditation, along with state programs including Louisiana and Virginia.
- Regulatory fluency. Products and services support EPA Method 30B, Performance Specification 12B, MATS mercury monitoring and Renewable Fuel Standard gas-quality compliance.
- Flexible ownership. Rental and lease programs suit short studies and pre-purchase evaluations.
