Gas Analyzer.

327-1 Flue Gas Analyzer. CO, temperature, draft, pressure.
327-1 Flue Gas Analyzer. O2, temperature, draft, pressure.
327-1 Flue Gas Analyzer. CO, O2, temperature, draft, pressure.
testo 327-1 is your introductory instrument to flue gas analysis. It measures combustion efficiency, flue gas loss, °C, O2, CO2, CO and flue draught. The strong LED background light in the 4 line display guarantees an easy-to-read display even if lighting conditions are unfavorable. The analyzer stands out on account of its easy menu navigation and ergonomic housing as well as its durability.
