testo 350-S
testo 350 is a versatile portablemeasuring system. The
measuring system consists in
principle of a Control Unit, a flue
gas analyser and a flue gas
probe, depending on the wishes
and requirements of the
customer.The testo 350-S flue gas analyseris equipped with a sensor for O
2 as standard. In addition, one
sensor must be fitted, or up to 5
additional sensors can be fitted.
The following
gas sensors areavailable for this purpose: NO
