Description
The TÜV-tested testo 330-2 LL is a high-performance professional flue gas analyzer engineered for comprehensive technical auditing, commissioning, and validation of domestic and commercial oil, gas, and solid fuel heating systems. Outfitted with a high-resolution 240 x 320 pixel graphic color display for on-site data mapping, the instrument integrates electrochemical Longlife gas sensors providing an extended lifecycle of up to 6 years. It features an integrated fresh air zeroing loop that functions directly inside the stack path without sensor extraction, alongside an automated dilution mechanism that extends the CO measurement threshold up to 30,000 ppm. The integrated software architecture supports advanced menu options, including gas pipe tightness diagnostics, piezoresistive draft mapping, velocity analysis via optional Pitot arrays, and multi-parameter data logging up to 500,000 readings.
Industrial Applications
- Official acceptation emission monitoring: Compliance verification of residential and industrial boilers matching strict 1. BImSchV and EN 50379 Parts 1-3 standards.
- Gas loop tightness diagnostics: Automated pre-set software routing to perform structural pressure drops and leak tests on gas supply pipe systems.
- Autonomous combustion tracking: Utilizing the internal logging memory array to record long-term emission curves, efficiency factors, and draft fluctuations.
