testo 330i – flue gas analyzer

Order-Nr. 0563 3000 70

The testo 330i flue gas analyzer is an advancement of the testo 330 LL flue gas analyzer. Its proven measuring technology is once again at the heart of the testo 330i. This means that you can rely on highly accurate results when measuring flue gas, draught and O2 supply air. The testo 330i also has the following impressive features:

  • User-replaceable long-life sensors with a service life of up to 6 years
  • Successful TÜV inspection according to the 1st German Federal Immission Control Ordinance (BImSchV) and EN 50379, Parts 1-3
  • ntegrated draught and gas zeroing. This means that the probe does not have to be removed from the flue gas duct for the zeroing
  • Fresh air dilution up to 30,000 ppm upon exceeding a CO threshold value

The new testoFix probe holder is available as an accessory, so the flue gas probe is guaranteed not to lose the centre of flow once it has been found. This can be attached to the pipe quickly and easily. It holds the probe in the centre of flow and also serves as a fall-proof suspension system for the testo 330i flue gas analyzer. Incidentally, the hose between probe and measuring instrument is lighter and more flexible than before.
