Testo 350 - Engine Kit for Combustion System Compliance Testing and Troubleshooting

The Testo 350 Engine Kit by Testo is an advanced portable flue gas analyzer configured for stationary engine testing, EPA-compliant stack emissions testing, and comprehensive combustion diagnostics on natural gas engines, diesel engines, gas turbines, and industrial combustion systems. It measures up to six gases simultaneously — O₂ (0–25% vol.), CO (0–10,000 ppm), NO (0–4,000 ppm), NO₂ (0–5,000 ppm), SO₂ (0–5,000 ppm), and hydrocarbons (CₓHᵧ) — with EPA-certified accuracy for regulatory compliance documentation. Designed for environmental consultants and emissions testing firms, it features an integrated printer, on-board data storage, and a rechargeable battery for full field portability.
