Overview
The NL-53 Class 1 sound level meter delivers industry-leading accuracy for professional acoustic measurement. This sound level meter combines sophisticated technology with intuitive operation, making them essential tools for environmental consultants, industrial hygienists, and acoustic engineers. From environmental impact assessments to workplace noise monitoring, these meters ensure compliance with international standards while providing reliable, reproducible measurements. Their versatile capabilities support diverse applications including:
- Environmental noise monitoring
- Occupational safety assessments
- Industrial acoustics evaluation
- Construction site noise measurement
- Community noise studies
Built to meet the demands of field work, these meters offer both durability and precision in a portable design. Fully complied with international standards IEC 61672-1:2013, ANSI/ASA S1.4.
Product line-up
- NL-53: Class 1 Sound Level Meter
- NL-53EX: Class 1 Sound Level Meter, NX-43EX (extended function program) pre-installed
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!
*NX-43EX needs to be installed to use this function.
Optional programs
NX-43EX Extended function program
With NX-43EX, some additional functions such as instantaneous value recording, measurement by trigger, comparator, LAN communication, and noise event tagging are unleashed. Installing NX-43EX is necessary before adding the NX-43WR, NX-43RT and NX-43FT.
NX-43RT Octave, 1/3 octave band analysis program
NX-43RT is real-time octave and 1/3 octave band analysis program
1/3 Octave band analysis
NC curve evaluation
Graph overlay
NX-43FT FFT analysis program
NX-43FT is FFT(Fast Fourier Transform) analysis program.

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.
