The Nor150 sound and vibration analyser is supplied with ½” preamplifier Nor1209 and the ½” measurement microphone Nor1225. It conforms to the latest revision of the following National and International standard including amendments, all type 1 / class 1; IEC61672, IEC60651, IEC60804, IEC61260, DIN45657, ANSI S1.4, ANSIS1.11, and ANSI S1.43.

Measured Parameters

  • Simultaneous measurement of SPL, Leq, LeqI, LMax, LMin, LE, LEI, LPeak, Ln and Tmax5.
  • Time weighting functions: Fast, Slow and Impulse (Simultaneous).
  • Spectral weighting functions: A, C and Z - weighting (Simultaneous).
  • Frequency analysis: 1/1 and 1/3 octave real time filters from 0,4 Hz to 20 kHz.
  • Statistical calculations: 8 individual adjustable percentiles from L0,1% to L99,9%, The statistical calculations are performed in real time within each frequency band and for each profile period if period length is set longer than 2 minutes. User can select between Fast or Slow time weighting as basis for the statistical calculation.

Measurement control

  • Time profile resolution: 10ms – 24 hours including full frequency spectra.
  • Overall measurement duration: 1 sec – 7 days. (If set to Repeat or Synchro mode a new measurement will be started automatically, with no time gap between each measurement.)
  • Back erase in Pause mode: 0-20 sec free selectable graphical back erase.

Audio recording
12 and 48 kHz sampling rate / 8 , 8MU, 16 and 24 bits / 5 sec pretrigger.

Measurement range

  • One range covering 120dB without any range adjustments.
  • Self noise measured with ½” microphone with a nominal sensitivity of 50mv/Pa: 17dBA.
  • Maximum RMS level 137dBA, Maximum Peak level 140dB PeakC.
  • The high SPL mode enables measurements up to 194dB using a suitable 1/4” microphone.
  • Built in GPS for position and exact time synchronization.

4,3” colour display, ¼ VGA with capacitive touch. Scratch-proof display glass with anti-smudge coating.
