The testo 310 flue gas analyzer combines simplicity and reliability. With an intuitive menu, four integrated measurement modes (flue gas, draft, CO ambient air, and pressure), a large backlit display, and compact design, it’s ideal for plumbing and heating professionals performing routine system checks.
Choose from five fuel types, making it suitable for furnace efficiency tests, boiler tuning, and water heater inspections.
The built-in magnet allows attachment to metal surfaces, freeing your hands. The sensor zeros in 30 seconds, filters are easy to replace, and the durable design protects against impacts. Condensate is simple to empty, and readings can be sent to the optional testo turbo printer via infrared for on-site documentation.

Draught measurement determines differential pressure between flue gas and ambient air, critical for low-pressure boiler systems. Correct draught ensures efficient combustion; too high increases flue gas loss, too low risks oxygen deficiency and soot formation.
Carbon monoxide (CO) is odorless, colorless, and poisonous. The testo 310 allows regular CO checks in areas around heating systems to ensure safety for people and compliance with safety standards.
Monitor CO, O2, and temperature in flue gases to track energy efficiency and pollutant output. Measurements help comply with legal limits and optimize heating performance. Data can be logged or transferred to a PC for record-keeping.
Measure flow and resting pressures on gas burners. Accurate readings prevent operational malfunctions and safety risks, ensuring that the burner functions correctly and efficiently.
Yes, it supports five fuel types, including gas, oil, and solid fuels, making it versatile for different heating systems.
The sensor can be zeroed in approximately 30 seconds, allowing quick setup for on-site measurements.
Yes, it has a rugged design that resists impacts and includes a condensate collection tank for convenient maintenance.
Yes, readings can be transferred to the optional testo turbo printer via infrared for immediate printouts.
Heating, plumbing, and HVAC service companies, as well as safety inspectors and energy auditors, find the testo 310 particularly valuable for efficient and accurate flue gas analysis.
