Why MRU

Best-suited to handle your gas analysis and monitoring needs.

In today’s regulatory and operational environment, accurate gas measurement is critical across every industry. Whether you’re managing emissions at power plants and manufacturing facilities, optimizing biogas and RNG production, monitoring landfill gas, ensuring HVAC system performance, detecting leaks, or maintaining process safety — MRU Instruments delivers the right analyzer for every duty cycle and every gas.

Decades of Experience

What started as a modest two-person operation is now an internationally-recognised corporation. Long before emission monitoring became the norm, MRU was developing tools to help plants, utilities, and renewable energy sites track and optimize their gas streams.

Expansive Catalogue

If you can name a particular gas analyzer application, chances are MRU carries it. Portable exhaust gas analyzers, biogas & RNG analyzers, landfill gas monitors, manometers, gas detectors, CEMS, HVAC combustion analyzers — find exactly what you need.

We Stand by Our Products

MRU stands unflinchingly behind every instrument we create. If any tool needs repair, calibration, or servicing, don’t hesitate to get in touch. We treat instruments as long-term investments.

Gas Measurement, Simplified

From emissions compliance to biogas maximization and safety monitoring, the right analyzer from MRU helps you stay compliant, increase efficiency, reduce downtime, and lower your environmental impact — no matter your industry.

Technology & Innovation

German engineering, measured to the part-per-million.

For four decades MRU has designed and built its own sensors, benches and software. That vertical integration is why our instruments hold accuracy in the field — today and many years from now.

01 In-house sensor development

NDIR & IR benches engineered and calibrated under one roof for traceable accuracy.

02 Multi-gas, simultaneously

Up to 7–9 gas components measured at once.

03 Connected reporting

MRU4U app & MRU4Win software for remote control, live data and compliant reporting.

04 Backed for the long run

Repair, calibration & service from a team that treats instruments as investments, not consumables.

Field Performance

Trusted by operators in the most demanding environments.

"The SWG 100 has been running 24/7 at our biogas site for three years without a single sensor failure. The reliability of MRU's German engineering is unmatched in the field."

Marcus Hoffmann

Technical Manager, BioEn Solutions

"We've switched our entire portable fleet to the NOVA plus. The modularity means my technicians can swap sensors in the field instead of sending units back to the lab for a week."

David Reynolds

Compliance Director, Gulf Coast Energy

"MRU's 48-hour service turnaround from their Texas facility is a game changer. In the industrial sector, downtime is lost revenue, and they understand that better than anyone."
