Explore practical guides to heating and combustion measurements, from boiler flue-gas testing to service diagnostics and gas-leak investigation. Learn what oxygen (O₂), carbon monoxide (CO), flue temperature and calculated combustion-efficiency figures can tell you—and what they cannot establish without appliance-specific limits.These articles cover sampling conditions, sensor checks, probe placement, safe measurement records, interpretation of changing readings and the differences between Testo analyzer models. They also examine combustion-air conditions, tightness testing, ambient CO monitoring and industrial emissions measurement. Use the relevant instrument manual and appliance service requirements for actual procedures; hazardous gas and combustion work belongs to qualified professionals.
testo 300: testo 300 Smart-Touch combustion analyzer combines O₂/CO flue measurements with on-device job documentation. The referenced 0633 3002 70.
testo 310: testo 310 is a compact combustion analyzer intended for routine heating service. Its compact field workflow differs from the 300.
testo 330: current testo 330 family has several sensor configurations: O₂/CO, CO with H₂ compensation, and configurations with an additional NO sensor. A.
testo 320: current testo 320 (0633 3200 01) has a 5.5-inch touchscreen and integrated O₂/CO sensors, with an advertised CO range to 5,000 ppm. The older.
NOx emissions testing measures nitrogen oxide compounds in exhaust gas under defined operating and sampling conditions. A reported NOx result is.
Flue gas analyzers combine measured combustion-gas values with calculated performance estimates. Oxygen (O2), carbon monoxide (CO) and flue-gas.
