Description
The TÜV-tested testo 330-2 LL professional long-life set is a heavy-duty master-level auditing kit engineered for technical commissioning, structural tuning, and legal compliance mapping on residential and industrial oil, gas, and solid fuel combustion loops. Built around a high-resolution 240 x 320 pixel graphic color display that visually maps complex data trends via integrated flue gas matrices, the analyzer utilizes user-replaceable electrochemical Longlife sensors boasting a service life of up to 6 years. The configuration features an electrochemical O2 sensor and a configurable CO measuring cell that achieves an expanded range up to 30,000 ppm through automated fresh air dilution triggered at 8,000 ppm, effectively protecting the grid cells from structural overload. It incorporates an single-hose multi-coupling mechanism to link all pneumatic and thermal paths in one motion, alongside integrated rear magnets and a large internal 500,000 reading storage capacity for advanced standalone diagnostic workflows.
Industrial Applications
- Official emission compliance tracking: Accurate testing of solid fuel, oil, and gas burners matching strict 1. BImSchV and EN 50379 Parts 1-3 regulatory parameters.
- Multi-point thermal plant auditing: Parallel diagnostics of stack flue factors (CO, O2, temperature), stack draft adjustments, gas flow pressure, differential lines, and 4 Pa fine pressure metrics.
- Long-term standalone profiling: Utilizing the internal data recording logic to monitor autonomous combustion trends up to 2 hours for detailed profile analysis checks.
