    • 30 to 120 dBA Measurement Range
    • ± 3 dB Accuracy; 0.1 dB Resolution
    • A-Weighting, C-Weighting & Fast-Time Weighting
    • Measurement Unit: SPL Actual, Leq, and Lmax
    • Accurate Sound Level Measurement
    • LED Alarm Indicator
    • 1.5~4 Years Battery Life
    • Easy Configuration (Via NFC)

    A & C Weighting as Needed

    Choose A-weighting or C-weighting based on scenarios. Usually, A-weighting is appropriate for quiet environments while C-weighting is for noisy environments.

    Fast-Time Weighting

    Fast-time weighting uses a time constant of 125 milliseconds for measuring unstable noise with large fluctuations.

    Fast weighting is turned off by default. When turned on, battery life will be shortened.

    More Sound Levels for more Insight

    Support reporting of three sound level values (maximum sound level, sound pressure level, and equivalent continuous sound level) based on different weighting methods.
