Digital sound level meter, measures sound levels from 30 to 130 dB, ideal for classrooms, streets and homes (battery not included).

Versatile Use: This digital sound level meter is ideal for measuring ambient noise in various locations such as factories, workshops, schools, residential areas, and offices. Perfect for applications in acoustics, quality control, and occupational health and safety, it ensures compliance with noise level standards in different environments. High Accuracy: Offering a measurement range of 30 to 130 dB with an accuracy of ±1.5 dB at 94 dB and 1 kHz, this sound level meter has a display resolution of 0.1 dB. This accuracy makes it suitable for professional environments and regulatory compliance. Fast/Slow Response Modes: With a simple press of the MODE button, users can switch between FAST and SLOW response speeds. FAST mode is useful for real-time monitoring of fluctuating noise levels, while SLOW mode provides average measurements, ideal for environments with stable noise levels. Advanced Features: The sound level meter records maximum and minimum sound levels, retaining data for over 3 seconds with a standard sampling rate of 0.5 seconds and a maximum margin of error of ±5%. The HOLD function freezes measurements on the screen for in-depth analysis, and an OVER/UNDER indicator signals any deviation from the measurement range, ensuring that all collected data remains within operational limits. Automatic shutdown: After 3 minutes of inactivity, the device automatically shuts down to conserve battery power.
