Functions and use
The testo 327 is a hand-held measuring instrument for the professional flue gas
analysis of domestic and light commercial gas and oil boilers and appliances.
This includes condensing boilers and gas heaters. The unit is designed to carry
out tests shown in BS 7967, and has a timed tightness test, let by test and a
timed CO function.
These systems can be adjusted using the testo 327 and checked for
compliance with the applicable limit values.
The testo 327 is available in four versions; the scope of function varies
according to the version:
· testo 327 O

· testo 327-1 (O2, CO):
Infrared interface
· testo 327-2 (O2, CO):
Infrared / IRDA interface, memory, automatic
sensor diagnosis, option: Bluetooth (data
