Nor1294 Phase verification coupler
Based on the innovative method invented by Norsonic to correct the phase response of a sound intensity analyser, the Nor150 offers the following outstanding unique features for sound intensity measurements; Measurement of the complete frequency response with the 12mm spacer with significantly higher dynamics than required in current ISO standards.
The procedure for this correction of the phase response is so conveniently integrated in the Nor150 that it can be performed very easily and quickly before each measurement!
For use with the Nor1290 Sound Intensity Probe.
