TESTO 340 User Manual

B. Intended purpose
This chapter describes the areas of application for which the measuring instrument is
intended.
The testo 340 is a handheld measuring instrument used in professional flue gas analysis
for:
· Engineers servicing/monitoring industrial combustion plants (process systems, power
stations)
· Emissions inspectors
· Engine manufacturers and operators
· Service engineers/mechanics of burner/boiler manufacturers in the industrial sector
Typical measuring tasks and particular characteristics of the testo 340 include:
· Measurement on industrial engines (CO/NO dilution)
· Measurement on gas turbines (high precision CO and NO plus optional dilution)
· Emissions measurement (integrated flow speed and differential pressure measurement)
testo 340 should not be used:
· for continuous measurements > 2 h
· as a safety (alarm) instrument
The testo 340 with the Bluetooth option may only be operated in countries in which it
is type approved (see Technical Data).
