The testo 300 is a measuring instrument for flue gas analysis on applications,
such as
•residential, commercial and industrial applications (oil, gas, wood, coal)
•low-temperature and condensing boilers
•boilers, furnaces and gas heaters.
Using the instrument, these systems can be adjusted and checked for
applicable limit values.
The instrument has been verified as a short-term measuring instrument and
should not be used as a safety (alarm) device.
The following tasks can also be performed using the instrument:
•Checking the O2, CO and CO2, NO, NOxvalues in combustion plants to
ensure optimum operation.
•Draft measurement.
•Measuring the gas flow pressure in gas heaters.
•Measuring and optimizing the flow and return temperatures of heating
systems.
•Measuring the CO concentration in the ambient air.
A NOxfilter for the CO sensor can be ordered as a spare part to replace a used
filter.
