Máy đo tiếng ồn âm thanh Rion NL-62

The NL-62 is the extended (low) frequency version of the  Rion NL-62 Rion’s cost-effective, feature-rich, upgradeable Class 1 platform for environmental noise.

The frequency range of the NL-62 is 1 Hz-20 kHz. The NL-62 also has G weighting in addition to Z, A and C weighting. There is a specific octave/third octave option for the NL-62, NX-62RT.
