Rion NL-62 Sound Level Meter

The NL-62 is the extended (low) frequency version of the Rion NL-52 sound meter – Rion’s cost-effective, feature-rich, upgradeable IEC 61672 Class 1 platform for environmental noise.

As such it shares the NL-52 features such as intuitive ease of use, data stored to CSV files on a memory card to facilitate importing data into Excel, a single 130 dB range, low power consumption and an excellent colour display.

This combination of extended (low) frequency range and full environmental logging capability (with audio recording, octave/third octave bands and FFT options available) makes the NL-62 a practical tool for investigating low frequency noise phenomena such as modulation noise from wind turbines.
