General Noise Meter (with Analyzer) 'NA-29' [Rental]

An integrated calibration of an averaging-type sound level meter and a real-time analyzer with a center frequency range of 31.5 to 8000 Hz, along with the addition of a memory unit and a calculation unit.

■ The analysis results are displayed in frequency vs. level and time vs. level. The display of time variation allows for the estimation of reverberation time. ■ Instant data and stored data are displayed together, making it easy to see the level differences for each frequency band at a glance. ■ Memory is backed up by a battery. ■ Equipped with a pause function. ■ Equivalent noise levels and other measurements are automatically taken within a range of 1 to 59 seconds, 1 to 59 minutes, and 1 to 24 hours using an internal clock. ■ Warnings for out-of-measurement range include overload, underload, and low battery voltage alerts. ■ The trigger function automatically stores analysis results that exceed the set level. ■ Markers display the absolute values of any frequency band level. ■ In addition to noise levels, octave band analysis can be performed for equivalent noise levels, maximum values, and noise exposure levels. ■ A wide-range integration average type sound level meter with a measurement range of 50dB displays noise levels in numerical and bar graph form on a 55×55mm display area. ■ Up to 1500 screens of measurement, analysis, and calculation results can be stored. The storage cycle for noise levels can be set in 11 steps between 2ms and 10s.
