Casella 630 Series Sound Level Meters

The Ultimate Tool for Noise Diagnostics

When general survey data isn't enough—when you need to understand exactly why a machine is loud or where environmental noise is leaking from—the Casella 630 Series provides the answer. As a Class 1 precision instrument, it offers the highest level of accuracy for legal and environmental applications. Its standout capability is real-time 1/3 octave band analysis. This breaks down the audible spectrum into narrow frequency bands, allowing engineers to identify specific tones or frequencies that are driving overall noise levels. This granularity is essential for designing effective noise enclosures, barriers, and damping materials.

Environmental and Engineering Applications

The 630 Series is versatile enough to bridge the gap between occupational safety and environmental compliance.

• Environmental Monitoring: For assessing noise pollution from industrial plants or construction sites affecting nearby residential areas, the 630 Series logs statistical parameters (Ln values like L10, L90) required by environmental regulations.
• Event Identification: Audio recording capabilities can be set to trigger on threshold exceedance. This means if you are monitoring a site remotely and a spike occurs, you can listen to the audio file later to determine if it was site noise or an external factor like a passing siren or thunderstorm.
• Tonal Analysis: The high-resolution frequency data helps in identifying tonal components in noise, which are often more annoying to the human ear and carry stricter penalties in environmental noise regulations.

Seamless Connectivity and Reporting

Managing large datasets from detailed surveys is made simple with the 630 Series. Like the other models in the range, it integrates seamlessly with Casella Insight software. The software allows for the detailed visualization of frequency data and time history profiles. You can zoom in on specific events, exclude artifacts, and generate comprehensive reports that detail compliance with specific local ordinances or corporate standards. The robust design, combined with sophisticated analytical power, makes the Casella 630 Series an indispensable asset for professionals dedicated to controlling noise at the highest level of precision.
