TPI 708A740 Combines the 708 Combustion Efficiency Analyzer with the A740 Infrared Printer - TPI Model 708 Combustion Efficiency 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.
All TPI analyzers feature quick and simple set up. Fast purge and the ability to perform fuel selectionduring start up enable tests to be performed quickly without requiring extra set-up time after initial startup. TPI analyzers also use the last selected fuel as the default setting. This feature prevents the need toperform fuel selection every time the analyzer is turned on.
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.
