Achieve Precision and Comprehensive Data Logging with a Professional Sound Level Meter

The SL-4036SD Integrating Sound Level Meter provides accurate and reliable measurements of sound pressure levels (SPL) with real-time data logging capabilities, making it an essential tool for various industrial, environmental, and occupational health applications.

Exceptional Features of the SL-4036SD:

1. Real-Time Data Logger: Saves measuring data along with time information (year, month, date, hour, minute, second) into the SD memory card, enabling easy download to Excel for further data analysis without extra software.

2. Comprehensive Measurement Modes: Measures SPL, Leq (equivalent continuous noise level), with over and under range indicating. The device supports both A and C frequency weighting and Fast/Slow time weighting, ensuring versatile noise assessment.

3. High Accuracy and Resolution: Features high accuracy (±1.5 dB at 31.5 Hz to ±2.5 dB at 16 kHz) and resolution (0.1 dB) for precise measurements across a wide range of sound frequencies (31.5 Hz to 16 kHz).

4. User-Friendly Design: Equipped with a large dot-matrix LCD with backlight for easy reading, and user-friendly controls including data hold, peak hold, max/min functions, and auto power off.

5. Advanced Connectivity: Includes RS232/USB PC computer interface for data output, enhancing data management and integration with other systems.
