Newly equipped with LAN terminals, the NL-53 series offer various enhanced functions to connect to other communication devices and to maximize the effectiveness of noise measurement tasks. The user interface is designed to be intuitive and easy to understand for the ultimate in user-friendliness.
3.5-inch Color LCD with touch panel,3 hardware keys Physically operated keys for reliable measurement execution.

The NL-53 series sound level meter and its LAN connectivity
facilitate the remote access enabling users to monitor noise

Case 1 Measurement site (e.g., wind turbine)
Case 2 Remote location such as office,Measurement site(e.g., machinery and equipment in a factory),*It is also possible to connect the LAN terminal of the sound level meter directly to a computer with a LAN cable and monitor the noise on a web browser.

Features

Intuitive operation without the need to refer to manual

Measurement display (Time-Level Graph) / Measurement display (instantaneous SPL, 2 channels)
Measurement display (calculated values) / Menu display
Water resistance - IP54 water resistant performance (except for microphone) Helps reduce risk of failure due to sudden rain showers, etc. Mounting the all-weather windscreen or rainproof windscreen boosts the water resistant performance of the entire unit, allowing the microphone to meet IPX3 specifications.
IEC - Comply with the international standards IEC 61672-1:2013, ANSI/ASA S1.4 Capable of various noise measurements Newly enhanced functions help achieve your tasks more comprehensively, with less effort

New Feature

New Feature - Simultaneous measurement for up to four channels.Set different frequency weighting and time weighting characteristics for each channel to record instantaneous SPL and calculated values. A single unit can measure up to 4 channels simultaneously, allowing users to reduce their working time.
New Feature : View and manage a unit's calibration history and save to SD card.Tracking changes in microphone sensitivity leads to reliable data management.

Optional program function list

Installing the optional programs adds the following functions:
Extended function program NX-43EX.Compatible models NL-43/NL-53/NL-63(pre-installed). *Note: Once installed, the NX-43EX program cannot be uninstalled.
*Note: Once installed, the NX-43EX program cannot be uninstalled.
Adding programs
Extended function program NX-43EX The NX-43EX allows users to add the NX-43WR, NX-43RT, and NX-43FT. Waveform recording NX-43WR,FFT analysis NX-43FT Coming Soon, Octave, 1/3 octave band analysis NX-43RT Coming Soon
Auto store function
This function allows simultaneous, automatic, continuous measurements in Lp (instantaneous value), Leq calculation (calculated values such as equivalent continuous sound pressure level, percentile sound levels, maximum sound pressure level). Each data is saved to an SD card in CSV format. Data can be managed using the AS-60 data management software for environmental measurements and loaded and displayed using spreadsheet or other software.
Lp store cycle Newly added function 10 ms, 25 ms

Following features are newly added to conventional model.

Three types of trigger functions
Measurement starts when a trigger is detected.
Level trigger,Timer Auto,External trigger
LAN function
Allows remote operation of the sound level meter and remote monitoring of real-time conditions.
LAN function
Four types of marker functions
Users can highlight sections for future lookup/reference.
Four types of marker functions
Leq, mov
Displays the calculated value of moving equivalent continuous sound level.
Wave form recording program NX-43WR - Compatible models NL-43* NL-53* NL-63 *NX-43EX required for NL-53/NL-43Wave form recording program NX-43WR - Compatible models NL-43* NL-53* NL-63 *NX-43EX required for NL-53/NL-43
*NX-43EX required for NL-53/NL-43
This function enables users to record sounds while processing sound levels.Recorded data can be played back on computers and used for frequency analysis (uncompressed waveform WAVE file). The data can be processed with waveform analysis software such as AS-70 for graphing, sound level calculations, frequency analysis, file output, and sound file playback. In addition, 240 Hz and 1200 Hz are added for NL-63. This realizes FFT analysis in higher resolution and longer recording duration in low frequency sound measurement.
Sampling frequency(24 bit or 16 bit) - Newly added function 240 Hz/1200 Hz - For NL-63 only
Other optional programs Coming Soon : FFT analysis program NX-43FT - Compatible models NL-43*/NL-53*/NL-63. Octave, 1/3 octave real-time analysis program NX-43RT - Compatible models NL-43*/NL-53*. Octave, 1/3 octave real-time analysis program NX-63RT - Compatible models NL-63. *NX-43EX required for NL-53/NL-43.
