Test Products International 708 - TPI Model Combustion Effincy Analyzer
The carbon monoxide sensor used in TPI combustion efficiency analyzers feature an on-board filter capable of filtering NO (nitric oxide), NO2 (nitrogen dioxide) and NOX (combination of NO and NO2) to prevent cross sensitivity errors.
Use TPI analyzers to test flue gases in gas and oil fired equipment including high efficiency furnaces and condensing boilers. Measure CO, O2, and stack temperature.
Determine combustion efficiency, CO2, and CO air free. Some models include built-in differential manometer, combustible gas detection, PC communication, data logging, and can measure NO / NOX.
- Measure CO, and temperature
- Calculate CO2, efficiency, excess air, and CO air free
Model 708 Features
Using TPI analyzers to determine combustion efficiency at the time of equipment set up minimizes call backs and can be used to verify to the home owner the value of service work by showing the increase in equipment efficiency after work is performed. Efficiency calculation can also be used to generate business by demonstrating the need to improve the efficiency of equipment or to show the benefit of purchasing new equipment with higher efficiency.
