Testo 340 Multigas Combustion Engine Tuning Analyzer
Rent the Testo 340 portable combustion analyzer for boiler tuning, furnace efficiency testing, and basic emissions measurements. This handheld flue gas analyzer measures up to four gases simultaneously, O₂ (0-25% volume), CO (0-10,000 ppm), NO (0-3,000 ppm), and NO₂ (0-5,000 ppm), with automatic combustion efficiency calculations and excess air measurements. Ideal for mechanical engineers, and facility maintenance teams performing routine combustion tuning and preventative maintenance on commercial heating equipment.
Designed for commercial boiler commissioning, gas engine testing, and burner optimization, the Testo 340 provides real-time flue gas analysis with on-board data storage and integrated printer for immediate documentation. Every rental ships fully calibrated with fresh sensors, sampling probe, printer paper, and all necessary accessories.
Rental includes: Testo 340 analyzer with up to 4 gas sensors, flue gas sampling probe with thermocouple, integrated printer with paper, rechargeable battery, AC charger, protective carrying case, calibration certificates, instruction manual, and technical support.
