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.

• Longlife Sensors: O₂, CO, and NO sensors with extended lifespan (O₂/CO replacement typically every 6 years)
