Testo 327-1
Flue gas analyzer, incl. rech. battery and calibration protocol; measures O2, CO, hPa, °C
testo 327-1 is your introductory instrument to flue gas analysis. It measures combustion efficiency, °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 unfavourable. The analyser stands out on account of its easy menu navigation and ergonomic housing as well as its durability.
