They are not gas analyzers, they use an electrochemical measuring principle or infrared (depending on the gas), with which it is possible to convert the measurement of gas's concentration in measurable electrical signal (4 ÷ 20mA or ModBus RTU485). Specifically designed for outdoor applications with IP65 enclosure. The measurable gases: NO2 (Nitric Oxide).
