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 wifi 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
By installing optional programs via SD card, you can add advanced functions to the device.
- Extended function program NX-43EX
- Waveform recording program NX-43WR
- Octave, 1/3 octave band analysis program NX-43RT (Coming soon)
- FFT analysis program NX-43FT (Coming soon)
* To install the optional programs, NX-43EX must be installed to the meter. It is pre-installed
NX-43EX is an extended function program. The NX-43EX allows users to add the NX-43WR, NX-43RT and NX-43FT.
NX-43RT and NX-63RT are real-time octave and 1/3 octave band analysis.
NX-34FT is FFT(Fast Fourier Transform) analysis program.
NX-43WR is waveform recording program.
- Allows recording of noise for playback and analysis.
- Useful for identifying and excluding unwanted noise.
- Enhances data accuracy and reliability.
