Sound level meter SL-10
Item no. 1662850
Intended use
The sound level meter is for measuring sound levels in the intensity range 30-130 dB.
It is a device used to check sound levels or for simple measurements of environmental sounds.
It is not suitable for use in laboratories or for scientific purposes.
The measurement signal is evaluated based on human hearing frequencies (A-weighting) in
the frequency range from 31.5 Hz to 8 kHz.
The measurement interval can be toggled.
The maxima or minima can be recorded.
In order to suppress disturbing wind noise, an attachable wind deflector is enclosed, which
does not affect the noise level measurement.
It operates on batteries.
It may only be used in indoor rooms. Contact with moisture, e.g., in bathrooms or the like, must
be avoided.
