--Combustion Efficiency Analyzers


Quick and simple set up
All TPI analyzers feature quick and simple set up. Fast purge and the ability to perform fuel selection during start up enable tests to be performed quickly without requiring extra set-up time after initial start up. TPI analyzers also use the last selected fuel as the default setting. This feature prevents the need to perform fuel selection every time the analyzer is turned on

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.
