Description
NA-28 is RION’s top sound level meter – analyzer. It combines cutting edge technology with excellent quality, speed and ease of use.
It features all the top capabilities that an acoustic consultant would need (measurement of all acoustic indeces, real-time 1/1-1/3 octave band analysis, data logging etc.)
NA-28 can expand its features with expansion cards for Waveform Recording, FFT, Building Acoustics.
Main features:
– Real-time 1/1-octave (16Hz to 16Hz) and at the same time 1/3-octave (12.5Hz to 20kHz) analysis
– Measurement data are stored in a CF card as text files (read by Excel and not requiring special software).
– It measures all the widely used acoustic indices (eq, max, min, 5 percentile indices LN, Peak, etc) in 1/1-octave and 1/3-octave analysis.
– Auto store of 300 000 data sets (e.g. 1000 hours per second of 1/3-octave analyses) in a CF 1Gb card (even greater in larger capacity cards).
– Simultaneous measurements in two channels (Main & Sub) with capability of different time/frequency settings in each channel.
– Data transfer using the CF card or/and USB cable
– Fully programmable
