E Instruments International

E Instruments International is a US-based manufacturer of portable combustion analyzers and gas detection equipment. The company focuses on instruments that measure flue gas composition and combustion efficiency in boilers, furnaces, engines, and industrial burners. Their analyzers measure key parameters including O2, CO, CO2, NOx, and SO2 to support emissions compliance and energy efficiency optimization.

The E8500 series and similar portable platforms are commonly used by HVAC technicians, boiler engineers, and emissions inspectors for on-site combustion tuning, regulatory compliance testing, and routine maintenance of heating systems. E Instruments analyzers combine multi-gas measurement with efficiency calculations in rugged, field-ready housings.
