The NL-53 features a precision condenser microphone that is capable of measuring sound levels from 25 to 141 decibels (dB) with a frequency range of 10 Hz to 20 kHz. The instrument is equipped with a large, easy-to-read LCD display that provides real-time readings of sound levels in decibels, as well as other key metrics such as frequency weighting, time weighting, and maximum hold.
Also available optional programs:
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.
FFT analysis enables sound level measurements for each frequency. The analysis frequency range is 20 kHz with frequency resolution of 2.5 Hz (8,000 spectrum lines). Saved analysis results can be loaded and shown in an overlay graph display together with current analysis data. The maximum zoom ratio is x40. The peak list display shows up to 8 peaks of frequency lines.
Both allow measurement compliant IEC 61260-1:2014. Electroacousutics – Octave-band and 1/N (fractional) - octave-band filters. It has a function to read out the saved analysis results, superimpose it on the graph being analyzed, display the graph of the NC curve required for evaluating indoor noise, and calculate and display the NC value. 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.
One of the key advantages of the NL-53 is its versatility. The instrument can be used in a wide range of applications, from measuring environmental noise levels to conducting occupational noise assessments in industrial settings. It is also ideal for measuring noise levels in music venues, auditoriums, and other performance spaces.
In addition to its measurement capabilities, the NL-53 also features a number of advanced functions that make it a valuable tool for sound measurement professionals. These include data logging and analysis capabilities, as well as the ability to interface with external devices such as computers and modems/routers for more detailed data (online) analysis and reporting.
The NL-53 is also designed with the user in mind, featuring a lightweight and ergonomic design that makes it comfortable to use for extended periods of time. The instrument is also built to withstand harsh environments, with a durable housing that is resistant to dust, moisture, and other environmental factors.
Overall Its accuracy, reliability, and ease of use make it a valuable investment for professionals. In case you want to measure lower frequencies, between 1 Hz – 20 Khz, NL-63 is a dedicated option. For class 2 measurements, the NL-43 is an interesting option.
