The fully featured testo 310 delivers more combustion parameters so you can get it right the first time - every time. Whether you need to perform basic combustion tuning, maintenance or safety checks, or install a new furnace or boiler the fully featured testo 310 delivers results.
Residential combustion analyzer
Rugged by design with more parameters
O2, CO (with NOx filter standard), CO2, draft, pressure, and more.
Bright backlit display
Five-line backlit display with two-line readout and easy-to-navigate menu structure.
Fastest startup available
Start testing faster - in only 30 seconds.
Quick exchange probe filter
Protect the instrument’s measurement accuracy with replacement filters.
Powerful magnets Powerful magnets on the 310’s housing allow for hands-free operation. Connected hose & probe Always ready for testing, the 310’s probe and kink-free hose is connected to the analyzer.
Combustion analysis in HD. Hi Def & Heavy Duty
Innovative features like the “flue gas matrix†will
graphically display the combustion characteristics. This is an
easy way show if the heating system is running efficiently
“in the green†or wasteful and unsafe “in the red.â€
For residential and commercial combustion applications
Color graphic display in HD with simple icon navigation
It is bright and easy to see, it’s easy to understand with simple menu icons.
Internal memory
Store up to 500 tests.
Pre-calibrated sensors
Typically last more than three years. Sensors are field replaceable and pre-calibrated.
More measurement options:
Ambient CO
CO sensors with NOx filter standard
Gas leak
CO2
And more...
Hardened cam-lock fittings
Provides leak-free operation and greater test confidence.
Two solutions for better combustion tuning.
The testo 310 & testo 320 make combustion analysis easier to perform, easier to control, and easier to understand.
testo 310 - Right the first time - every time.
The testo 310 residential combustion analyzer represents a new class of instruments for Testo and provides exceptional value and expanded capabilities in combustion testing.
testo 320 -Comprehensive combustion analysis. The 320 is designed for the job site and for the contractor that expects more. Use it for basic testing and tuning of all types of boilers, heater or furnaces. Use it to set up and commission more complex multi-stage, or modulating heating systems.
testo 320 combustion analyzer kit with printer:
Includes: testo 320 combustion analyzer with rechargeable battery, 12 inch probe with cone and hose, AC power supply (with USB recharging), IR printer, long life thermal paper rolls (6), spare particulate filters (10), and rugged case
