• We cope with long-term measurements such as environmental measurements  Record more than 1,000 hours (approximately one month) is possible.
• Auto store function Continuous recording of

  Lp (instantaneous value) and L eq calculation (calculated values such as equivalent noise level, hourly rate noise level, and maximum value) can be performed at the same time. Each data is saved in the SD card in CSV format. In addition to managing data with the environmental measurement data management software AS-60, it can also be displayed using spreadsheet software.

• Three types of trigger functions Level trigger/timer auto/external trigger Three types of trigger functions
  Start measurement when a trigger occurs.
  
  
• LNA function  It is possible to operate and grasp the situation from a remote location.

• Waveform recording program NX-43WR

The recorded data can be played back on a computer and supports frequency analysis (uncompressed WAVE files).
Waveform processing software AS-70 enables graph display, level processing, frequency analysis, file output and playback of analysis results.

• FFT analysis program NX-43FT (to be released)

FFT analysis can be performed to measure the loudness of each frequency.
Analysis frequency range is 20kHz, frequency resolution is 2.5Hz (8000 lines).
It is possible to read out the saved analysis results and display them overlaid on the graph being analyzed.
Up to 40x zoom magnification and 20 peak lists can be displayed.

• Octave/1/3 octave real-time analysis program NX-43RT (to be released)

Measurements conforming to JIS C 1513-1: 2020 "Octave band and 1/N octave band filter" are possible.
Equipped with a function to read out the saved analysis results, display them overlaid on the graph being analyzed, display graphs of NC curves required for evaluating indoor noise, and calculate and display NC values.
Using the environmental measurement data management software AS-60RT enables recalculation and data management on a computer.
It is also possible to output the voltage (AC out, DC out) of the arbitrarily selected band.
