Testo 330-2 LL Pro Flue Gas Analysis Kit
Product Introduction
The Testo 330-2 LL is a TÜV-tested flue gas analyzer designed for
comprehensive heating system diagnostics. Engineered with longlife
(LL) sensors, it offers extended durability and cost savings by
reducing sensor replacement frequency (e.g., O₂ sensors every six
years). This versatile tool combines precision measurements with
user-friendly features, making it ideal for professional
technicians performing installation, service, and maintenance on
heating systems. With a 4-year warranty and advanced
functionalities like automatic CO thinning and integrated data
logging, the 330-2 LL sets a standard for reliability in flue gas
analysis.
