Máy đo tiếng ồn class 1 NA 28 RION
The Rion NA-28 is the quickest and easiest to use Class 1 multi-function sound analyser for Building/Architectural Acoustics and Environmental Noise. The superb colour display is visible in all lighting conditions and data is saved to a memory card in CSV format.
The colour display is used to full advantage for the NX-28BA Building Acoustics option which provides both airborne and impact sound insulation testing results in the meter.
Background and receiver room levels are shown on the same display together with colour-coded indication corrected third octave bands or where the difference is less than 6 dB.
