Digital Noise Sound Level dB Meter Decibel PC CD USB

Digital Noise Sound Level dB Meter Decibel PC CD USB

This digital meter is a multifunction sound level meter designed to accurately measure environmental noise, such as the noise from mechanic, vehicle, ship, loudness of computer fans and other noise with ¿¿2 dB accuracy in decibels (dB).

This unit was designed according to the IEC651 TYPER2 & ANSI S1.4 TYPE2 for sound level meters. Instantaneous sound measure function. With two equivalent weighted sound pressure levels, A and C. Fast & Slow dynamic characteristic modes. AC and DC signed output for frequency analyzer level recorder, FFT analyzer, graphic recorder etc.
