Integrating Sound Datalogger

Sper Scientific Integrating Sound Datalogger (Model 850020)

Accurately Monitor and Analyze Sound Exposure Over Time

Ideal for industrial safety, environmental noise monitoring, and acoustic analysis, Sper Scientific’s Integrating Sound Datalogger (Model 850020) is a high-performance instrument designed to measure and record sound pressure levels (SPL) over extended periods. By integrating weighted SPL measurements, it precisely calculates the time-weighted average (TWA) and cumulative sound exposure (LEQ), providing essential data for OSHA compliance and hearing conservation programs.

Comprehensive and User-Friendly Display The device features a large, bright, backlit display that simultaneously shows all critical test parameters, including real-time SPL, LEQ, maximum/minimum values, and exposure time. A high-resolution 0.1 dB display and a responsive bar graph offer an intuitive visual representation of changing sound levels, allowing for immediate assessment.

Advanced Features for Professional Use

• Single Dynamic Range: A wide 30 to 130 dB range eliminates the need for manual range selection, preventing data errors that can occur during range changes in auto-ranging models.
• Selectable Weightings: Choose between A and C frequency weightings to suit different applications—'A' weighting for human ear perception and 'C' weighting for flat response measurements.
• Time Weighting: Switch between FAST (125ms) and SLOW (1s) time weightings to capture either peak noise or average noise levels.
• Alarms: Set custom over-limit and under-limit alarms to receive instant notifications when sound levels exceed predefined safety thresholds.

Powerful Datalogging and Software Integration With the capacity to store up to 64,000 data records directly on the meter, you can conduct long-term environmental or workplace monitoring without interruption. The included software and bidirectional USB interface allow you to:

• Download and Analyze: Easily transfer, save, graph, and process your collected data on a computer.
• Real-Time Control: Control the meter remotely via its on-screen image directly from your PC, enabling you to start/stop recording, adjust settings, and monitor readings without physically touching the device.

Compliance and Accuracy The Integrating Sound Datalogger is engineered for precision, with an accuracy of ±1.0 dB. It meets or exceeds the rigorous standards for an IEC 61672:2013 Class 2 and ANSI S1.4:2014 Type 2 meter. For maintaining certified accuracy, the unit can be calibrated in the field using Sper Scientific's Acoustical Calibrator 850016, ensuring full compliance with OSHA and other regulatory requirements.

Complete Kit Your datalogger comes ready to use in a foam-lined, protective carrying case, complete with:
