Combustion Analyzers & Emissions

Combustion analyzers measure flue gas composition, including O₂, CO, NO, NO₂, and SO₂, to verify combustion efficiency, tune equipment, and document emissions compliance. They are commonly rented for boiler tuning, furnace maintenance, engine emissions testing, and EPA-compliant stack testing on industrial combustion systems. Our fleet includes the Testo 340 for routine combustion tuning with up to four simultaneous gas channels and the Testo 350 for advanced regulatory work with up to six channels, including SO₂ and hydrocarbon (CₓHᵧ) measurement. Every analyzer ships with the probe, filters, and sampling setup matched to your application, and our technical team can walk you through warm-up, zeroing, and field technique so your data is clean and report-ready.
