HIGHLIGHTS
The new sound level meter is designed to be compact, lightweight and easy to use.
This technology extends the lower limit of the measurement range to lower than 0 dB-SPL.
It complies with the type 2 ANSI S1.4 1983 standard , and has an innovative, unique 0-dB feature that eliminates the selfnoise of the microphone.
