• Leq, Lmax, Lmin, LCpeak, Ln statistics for comprehensive documentation
• Time history logging with adjustable intervals to reveal patterns and trends
• Optional octave band analysis to identify dominant frequencies and guide controls

Field-Friendly Operation

• Intuitive menus and clear displays support confident, fast decisions
• Durable housings and long battery life suit demanding environments
• Simple calibration routines promote consistent data quality

Reporting and Collaboration

• Robust onboard storage for multi-site projects
• Quick data exports to streamline reports and share results
• Templates and consistent workflows for repeatable outcomes

Use Cases

• Program audits and annual assessments
• Diagnostics for enclosures, barriers, and damping treatments
• Construction and project monitoring with changing conditions
• Boundary surveys with clear documentation for stakeholders

Choosing the 620 Series

• Select Class 1 for the highest accuracy and diagnostic studies
• Select Class 2 for routine assessments and program checks
• Add octave band analysis when frequency content informs control design
• Consider memory and logging interval settings based on project duration

The Casella 620 Series helps you move from basic readings to actionable insights — turning time history and frequency detail into clearer priorities for noise control strategies and more persuasive communication with decision-makers.
