Overview
The NL-63 Class 1 sound level meters is capable of infrasound from 1 Hz. Not only by being equipped with the dedicated microphone, but also featuring the necessary functionality for infrasound measurement such as G-weighting to assess the low frequency noise correctly. As it has the same communication functionality as its same production series NL-53, NL-63 can be your reliable measurement partner in the fields such as wind turbine noise measurement. Fully complied with international standards IEC 61672-1:2013, ANSI/ASA S1.4.
Features
Touch panel screen
With fully touch panel screen, you can easily access to the function and operation command that you seek. The essential operation such as power on/off and start/stop measurement are still controlled with a physical keys. This design is based on philosophy that reliability is the key to noise measurement.
Feature-packed Interface
USB Type-C connector enables power supply from portable battery and data transfer. LAN Terminal for connecting to a network.
Web browser function
You can remotely access to your sound level meter via web browser after establishing the network connection. The connection can be established via LAN cable directly connected to the meter, or mobile wi-fi router for remote connection. This helps you to optimize your measurement procedure.
The measurement value is showed on the screen, you can access to the setting menu, and saved data can be downloaded from SD card. You can remotely what dB level is detected by you sound level meter in Leq, Lmax, LE, LT, and so on. For example, “the current noise level is 55dB and it is close to the threshold”. It is also beneficial for you to see your dB meter is working properly!
Optional programs
*The NX-43EX is not available for NL-63 because NL-63 has the functionality of NX-43EX as it comes.
NX-63RT Octave, 1/3 octave band analysis program
NX-63RT is real-time octave and 1/3 octave band analysis program that is capable of frequency of infrasound.
1/3 Octave band analysis
NC curve evaluation

NX-43WR Waveform recording program
- Allows recording waveform of noise for playback and analysis.
- Event recording function enables only recording the waveform for the noise event that exceeds preset level.
- Waveform analysis software AS-70 allows you to post process of noise data from the waveform into FFT and Octave band analysis with variable preferences.
