Product Description

Sound Level Meter

FIVE DIFFERENT MEASUREMENT MODES
- Mode 1 : Conventional sound level meter
- Mode 2 : Conventional sound level meter with storage.
- Mode 3 : Conventional and integrating-averaging sound level meter
- Mode 4 : Integrating-averaging sound level meter with storage.
- Mode 5 : Sound level meter “calculator” of two sound sources.

MEASURED VALUES
- Weighted sound level : L                         - Sound exposure level : LE
- Equivalent continuous level : Leq                - Peak pressure level : Lpk

RESULTS & ADDITIONAL INFORMATION
- Maximum and minimum values, peak values
- L01-L10-L50-L90 statistics distribution of measured values.
- Presence and percentage of overload input stages, measurement time.
- Residual autonomy of batteries or battery, measuring capacity remaining.
