This high-quality, professional digital sound level meter is very simple to operate. It can be used for all measurements of volume-ranges of 35 dB up to 130 dB. These measurements can be passed on to external devices by a 3.5mm jack socket.
The sound pressure level measurements work with the two most important frequency evaluation filters A and C, (A: Frequency rate that is modelled on the human hearing, C: Band-pass with edge frequencies 31.5 Hz and 8 kHz).
