Description
Introduction:
NA70 is a multichannel noise measurement and analytical instrument discretionarily combining noise and vibration measurement。It can achieve the real-time measurement of noise and acceleration and other physical quantities..High-speed computing by PC, high-capacity storage capacity, analyse and calculate the time domain and frequency domain of the collected signal.It has much advantages such as multiusage,high precision,etc. Can be widely used in environmental noise measurement, ambient vibration measurement, the spectrum analysis of 1 / 1, 1 / 3 noise source, real-time FFT analysis, architectural acoustic measurement.
NA70Multichannel noise / vibration analyzer is composed of computer, package, high speed A / D board, measuring amplification board, charge amplification board, accelerometers, preamplifier, measuring microphone
