Setting a new standard in reliable combustion tuning - the testo 310

Get your readings right - every time: The testo 310 provides accurate measurements for O2, CO (with built-in NOx filter), CO2, undiluted CO (CO air free), ambient CO, draft & pressure, temperature (flue & ambient) and excess air for applications like checking boiler efficiency, tuning and water heat checks.
