Casella CEL-620A Series Sound Level Meter TSI

Model: CEL-620A1 | Advanced Digital Sound Level Meter for Workplace Noise Assessment

The Casella CEL-620A Series Sound Level Meter  TSI is a professional-grade instrument designed for accurate workplace and environmental noise assessments. Featuring a high-resolution color display and user-friendly interface, the CEL-620A simplifies complex noise monitoring tasks, making it ideal for industrial hygiene professionals, occupational safety experts, and environmental health practitioners.

Engineered for compliance with major international noise regulations, including EU directives, OSHA, and ACGIH standards, the CEL-620A measures all critical workplace noise parameters in real time. It is suitable for a range of applications such as occupational noise exposure analysis, machinery noise testing, and hearing protection selection.

With its robust design, intuitive setup, and selectable time history storage, the CEL-620A combines reliability and flexibility. The device automatically stores all measurement parameters, including LEQ, LAVG, and LPeak, whether selected or not, and can record up to 999 individual sessions with runs lasting up to 24 hours each.

This model includes voice note functionality, GPS location tagging, and automatic calibration using the CEL-120 Series Calibrator, allowing for fully traceable and accurate data logging. Measurement screens are color-coded for ease of operation—green while active, red when the run ends—ensuring efficient data collection at every step.
