TPI 709 Combustion Efficiency Analyzer, 3 x AA Batteries, 3 Line Backlit LCD Display, 14 to 122 Degree F

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 startup. 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. Built-in differential manometer with 0.001" H2O resolution. Calculates combustion efficiency. Pump driven for fast response. Will not shut off if 15 ppm CO is present for increased safety. Optional A740 IR. printer available for hard copies of test results. Built-in differential thermometer. Store function to save up to 50 readings. Push on fittings for fast and easy use. Large easy to read backlit display. Ten selectable fuels. Operating temperature range: 14 to 122 degree F.
