Description
The TÜV-tested testo 330-2 LL Pro kit is an intelligent, high-performance professional flue gas analyzer engineered for extensive diagnostics, commissioning, and maintenance inspections in and around heating plants. Outfitted with a high-resolution color graphic display that presents advanced diagnostic visualizations, such as the flue gas matrix and line progression diagrams, the device utilizes user-replaceable electrochemical Longlife sensors that operate reliably for up to 6 years. Unlike basic models, it features integrated fresh air zeroing directly within the stack exhaust path without sensor extraction, alongside an automated dilution system that dynamically expands the CO determination matrix from 8,000 ppm up to 30,000 ppm. The instrument supports parallel draft, data logging (up to 500,000 readings), differential pressure variations, and connection to secondary leak detection probes via a heavy-duty bayonet connection lock.
Industrial Applications
- Official emission compliance tracking: Accurate testing of residential, commercial, and industrial burners matching strict 1. BImSchV and EN 50379 Parts 1-3 regulatory parameters.
- Comprehensive burner and pipeline inspection: Dynamic diagnostics of flue gas factors (CO, O2, temperature), stack draft adjustments, gas flow pressure, and core velocity.
- Safety and isolation auditing: Advanced cross-menu utility routing for ambient CO accumulation tracking and gas pipe tightness validation procedures with standalone optional sensors.
