The document describes the testo 360 portable reference flue gas analyzer. [1] The testo 360 provides accurate measurements of flue gas parameters like O2, CO, NO, NO2, SO2, and CO2 that are compatible with stationary analyzers. [2] It is designed to withstand harsh industrial conditions with high temperatures, dust, and long-term use for emission testing and combustion system maintenance. [3] The system includes a rugged analyzer unit, notebook computer for operation and data storage, and a selection of industrial flue gas probes for different temperature ranges.

Technical data
General measuring ranges
In testo 360 the measuring range end value is determined by the choice of test gases. Example: CO desired measuring range up to 300 ppm => test
gas concentration approx. 240-260 ppm (approx. 80 % of measuring range end value). However, the recording of measurement values over the
measuring range thus defined is possible.
