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 system s can be adjusted and checked for
applicable limit values.
The instrument has been verified as a sh ort-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 O
ensure optimum operation.
• Draft measurement.
• Measuring the gas flow pressure in gas heaters.
• Measuring and optimizing the f low and return temperatures of heating
systems.
• Measuring the CO concentration in the am bient air.

9.6.12 Pipe Commissioning (EU regulation)
The pipe commissioning (using air or inert gas such as CO2 or N2) is a tightness
test for pipes, including fitting s , but without gas appliances and the relevant
regulating and safety devices. T he pipe commissioning is performed after a load
test has been successfully complet ed on newly laid gas pipes, or after
renovation of existing gas pipes, and is used for the acceptance of these pipes.
It shows up even the smallest leaks in gas pipes.
According to DVGW TRGI 2008 and ÖVG W G10, the stabilization time
and test time depend on the pipe volume.

- Pipe volume > 100 l to < 200 l: Adjustm ent time 30 min, test time

When replacing an O2 sensor and when there is an interruption of the
power supply for more than 10 hours, we recommend an
acclimatization time of 1 hour for c ompliance with measuring accuracy.
