Integrating Sound Datalogger, NIST Certificate

Integrating Sound Datalogger, NIST Certificate

Sper Scientific’s Integrating Sound Datalogger is a professional-grade instrument designed to accurately measure and record sound pressure levels (SPL) while meeting strict compliance standards. This meter is an essential tool for calculating cumulative sound exposure (LEQ) and ensuring workplace safety, environmental monitoring, and compliance with regulatory requirements like OSHA.

Advanced Features for Reliable Sound Monitoring

The Integrating Sound Datalogger uses advanced technology to measure SPL according to both A and C weightings, integrating these readings over a specified time period—such as an 8-hour workday—to calculate cumulative sound exposure (LEQ). The large, bright, backlit display simultaneously shows SPL readings, LEQ calculations, and test parameters with 0.1 dB resolution and an intuitive bar graph for quick visual analysis.

With a wide dynamic range of 30 to 130 dB, this meter eliminates the need for manual range selection, preventing data errors often caused by range switching. The device also features fast and slow time weighting, over-limit and under-limit alarms, and USB connectivity for seamless data transfer and remote control. It stores up to 64,000 data records, which can be saved, graphed, and analyzed using the included software. The USB port also allows bidirectional communication, enabling control of the meter directly from a computer screen.

Unmatched Accuracy and Compliance

Accurate within ±1.0 dB, the Integrating Sound Datalogger meets or exceeds all requirements for IEC 61672:2013 Class 2 and ANSI S1.4:2014 Type 2 standards. This ensures the highest level of reliability and precision for professional use. To further enhance its credibility, this meter is calibrated and tested to ensure compliance with specifications traceable to the National Institute of Standards and Technology (NIST).

NIST Calibration Certification: Every new Sper Scientific Digital Sound Meter includes a Certificate of Calibration, confirming that the instrument was tested in Sper Scientific’s in-house lab. Calibration is performed using NIST-traceable instrumentation and standards, ensuring superior accuracy and integrity. Each certified product comes with:

• A unique serial number
• A certification label
• A detailed certification testing report

These rigorous testing and certification practices make the Integrating Sound Datalogger a trusted tool for applications requiring precise sound monitoring.
