The detachable control unit can control the analysis system and read out data. The testo 350 XL control unit can also be used as a separate hand-held analyzer for differential pressure (built-in) and also for temperature, humidity, flow etc. thanks to its additional probe socket. Readings are printed on the built-in printer .
The flue gas analyzer is the “heart” of the analysis system and is available in two different versions:
• testo 350 S Basic version
• testo 350 XL Advanced version.
The testo 3 350 S flue gas analyzer is equipped with a gas sensor for O2 as standard. One sensor must be fitted or up to 5 additional sensors for NO (option), NO2 (option), SO2 (option), NOlow (option), CO (Option), COlow (option), H2S (option), HC (Option) or CO2 via infrared gas sensor (option) can be fitted.
Temperature and differential pressure as well as the usual parameters such as ∆, qA, etc. are also calculated.
The even more convenient testo 350 X XL flue gas analyzer is equipped with gas sensors for O2, CO, NO and NO2 as standard. Additional sensors for HC (option), NOlow (option), COlow (option), SO2 (Option), H2S (option) or CO2 via infrared gas sensor (option) are available. In addition to the features of the S version, the testo 350 XL flue gas analyzer also has a Peltier gas preparation unit with a hose pump to regulate condensate disposal as well as a fresh air valve for long-term measurements lasting several hours.
Both versions of the flue gas analyzers can be equipped with up to 6 gas sensors, have a built-in rechargeable battery as standard, (for battery operation), data logger (250,000 readings) as well as a Testo data bus connection.
The testo 350 S flue gas analyzer can be retrofitted with all the features/functions of the testo 350 XL flue gas analyzer
