Featuring a large 4.3” true colour touchscreen, the Nor150 provides the user friendliness of a smartphone.
Further features include; two measurement channels, built in web server, camera, GPS and advanced voice and text notes bringing the sophistications normally found in laboratory instrumentation out in the field. Connect your smartphone, pad with NorVirtual App installed and take full control of the instrument. Add photos and voice notes obtained on your smartphone or pad seamless integrated with markers to your noise data. Nor150 can also be controlled via NorCloud, Nor850 software, NorRemote and NorVirtual for PC . NorConnect is the tool you use to download, view and generate excel reports of your measurements.
The Nor150 can be used in the following situations:
- Environmental noise
- Building acoustics
- Sound intensity
- Noise monitoring
- Product noise testing
- Noise in the workplace
- Noise nuisance recorder
- Front end for Nor850
- General noise and vibration measurements
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.
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.
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.).
