Sound Meter - Type 1 Datalogger with SD Card

Sper 860071 Sound Meter - Type 1 Datalogger with SD Card

Achieve precise and reliable sound level measurements with the Sper 860071, a Type 1 Sound Meter and Datalogger designed for professionals. This high-performance instrument meets the rigorous IEC 61672-1:2013 Class 1 and ANSI S1.4-2014 standards, ensuring top-tier accuracy for critical applications. It is the ideal tool for environmental noise assessments, occupational health and safety (OSHA) compliance, industrial noise monitoring, and acoustic engineering.

With its real-time data logging capabilities and an included 16GB SD card, the meter allows for seamless recording of sound pressure levels (SPL) and equivalent continuous noise levels (Leq). Data is saved in a universal CSV format, complete with timestamps, making it easy to download and analyze in spreadsheet software like Excel without needing proprietary programs.

Key Features:

• Real-Time Data Logger: Effortlessly record and save measurement data directly to an SD memory card. Each entry is time-stamped (year, month, date, hour, minute, second) and can be easily transferred to a computer for in-depth analysis.
• Comprehensive Measurement Modes: The device measures SPL and Leq, with clear over-and-under range indicators. It supports both A and C frequency weighting to suit different measurement needs—'A' weighting for environmental and workplace noise, and 'C' weighting for analyzing machinery noise. Users can also select Fast or Slow time weighting for versatile noise assessment.
• Exceptional Accuracy and Wide Range: Delivering Class 1 accuracy (e.g., ±0.7 dB at 1 kHz), this meter provides precise and repeatable results across a broad frequency spectrum (31.5 Hz to 16 kHz) and a dynamic measurement range of 30 to 130 dB.
• User-Friendly Design: A large, backlit dot-matrix LCD ensures clear visibility in any lighting condition. The interface is intuitive, offering essential functions like Data Hold, Peak Hold (to capture maximum values), and Max/Min recording. Auto power-off helps conserve battery life.
• Advanced Connectivity: Features an RS232/USB PC interface (cables optional) for real-time data streaming or batch downloads, allowing for seamless integration with other systems for advanced data management.

Additional Specifications:

• Measurement Modes: SPL, Leq
• Measurement Range: Auto range (30-130 dB) and two manual ranges (30-80 dB, 80-130 dB)
• Functions: dB (A & C frequency weighting), Time weighting (Fast, Slow), Peak Hold, Data Hold, Record (Max, Min.)
• Microphone: High-stability ½ inch electric condenser microphone.
• Data Logging:
  • Auto Mode: Sampling time is adjustable from 1 to 3600 seconds.
  • Manual Mode: Save a data point with a single button press.
• Storage: Supports 1GB to 16GB SD cards (a 16GB card is included). Data is saved in CSV format for universal compatibility.
• Calibration: Features an external calibration VR for easy adjustment with an optional sound calibrator (like the SC-942).
• Outputs: AC output (0.5 Vrms) for connection to external devices like frequency analyzers.
• Power: Powered by (6) AA batteries (included) or an optional DC 9V adapter.

What's in the Box?

The Sper 860071 comes complete with a hard-shell, foam-lined carrying case, a 16GB SD card, a fold-out desk stand, user manual, and (6) AA batteries.

For Optimal Results: This instrument includes a built-in tripod mount. For the most stable and accurate readings, especially during long-term monitoring, we highly recommend using a tripod.
