TPI DC711 Flue Gas Analyser
The TPI DC711 Flue Gas Analyser combines combustion gas sensing, pressure testing and temperature measurement in one portable instrument. It measures oxygen and carbon monoxide while calculating carbon dioxide and combustion efficiency. Engineers can therefore carry out several important heating system checks without changing between separate tools.
Built for regular field use, the analyser has a backlit graphic LCD and a simple navigation menu. Users can hold readings, store up to 100 reading sets and review recorded results when required. A 24-hour real-time clock also supports clear and organised test records.
Support for several fuel types makes the TPI DC711 Flue Gas Analyser suitable for varied domestic and commercial heating systems. Pressure and tightness functions help engineers assess system condition, while differential temperature measurement supports flow and return balancing. Optional high-range CO and NOx sensors can extend the instrument for more demanding measurement work.
