Nor 121 Multi-function Analyzer with two microphones £ 39 a day *

A dual channel analyzer to measure both noise or noise and vibration simultaneously.

Statistical [Ln] functions of the broad band spectral networks and each 1/3 octave or 1/1 octave frequency band from 0.1 Hz to 20 kHz for all three major time constants. Up to 1400 different parameters may be recorded.

When used in the single channel mode the dynamic range may be set to > 120 dB.
Large paper white screen for graphical and numerical displays

Internal hard disk drive [4 Gbytes] with Digital Audio Recorder function for storage of raw acoustic data. The disk is also partitioned for storage of measurement results, setup menus and monitor microphone to record the operators comments.

With seven levels of nested reports and a timer function, the analyzer can report literally thousands of different rating parameters, including overall global values and time profiles in both the time and frequency domain. The instrument can run for weeks collecting 1 second third octave spectra without filling its memory *.

Rechargeable batteries, multiple interfaces, PCMCIA, RS-232 and Centronics. Internal multi frequency oscillator for outdoor microphone verification, compatible with the GRAS 41AL Outdoor Microphone Systems.
