The testo 300 / testo 300 Pro is a combustion analyzer that can measure the temperature, oxygen content, carbon monoxide content, carbon dioxide content, nitrogen oxide content and particulate matter content of combustion gases.
The Testo 300 and Testo 300 Pro are measuring instruments designed for flue gas analysis in residential, commercial, and industrial applications, including oil, gas, wood, and coal systems. The device allows users to check O2, CO, CO2, NO, and NOx values to ensure optimum operation of combustion plants. It also supports draft measurement, gas flow pressure measurement, and ambient CO concentration measurement. The instrument is verified as a short-term measuring instrument and should not be used as a safety alarm device.
