Norsonic 110 Sound Level Analyzer
| Nor 110 | Real Time Analyzer - multi-function - type 1 | £ 22 a day * |
Multi-function precision sound level analyzer.
Simultaneous measurement of SPL (Fast, Slow, Impulse, Peak+ and Peak-) as well as Leq, SEL and all the Ln values.
Graphical & numerical displays.
Real Time digital filters - 1 Hz to 20 kHz
Eight channel electronic level recorder.
Vibration measurements option with engineering units + whole body and hand arm networks.
Results may be automatically stored in the large non volatile memory and / or transferred to a PC using the Nor 1020 Nor-Xfer software.
In the event of a 'flat' battery the last thing the Nor 110 does is to store the results in the non volatile memory.
The built-in options include
- Level Mode - general purpose level measurements, various parameters measured simultaneously
- Filter Mode - real time 1/3 and 1/1 octave filters, 1 Hz - 20 kHz. Graphical and table displays. Serial filters included with automatic scan or manual selection
- Reverberation Mode - calculates EDT, RTs and presents curves and tables
- Time Mode - converts the analyzer into an 8 channel level recorder, plotting and storing the time histories of the Leq, Peak etc + L10 or other percentiles. During measurements, events may be tagged to establish the noise climate with and without specific noise sources
- Sequence Mode - programmable measurement sequences
- Event Mode - 4 x- level measurements with event detection and store / print
- Narrow Band - 1/12, 1/6 octaves - selectable frequencies
- Percentile Spectra - Ln values for each filter bands - in 0.1 dB steps
- Statistics Mode - all Lns with adjustable class widths with graphical and numerical plots. Operates in level, time and event modes
- Vibration Networks + Engineering Units - vibration measurements in absolute units and weighted according to the various British and ISO Standards - includes hand arm and whole body networks. Order an accelerometer separately, if required
Norsonic 110 Specifications
Delivered with a precision measurement microphone, preamplifier, 2 m microphone extension cable, all the options listed above, rechargeable batteries, a mains / charger, windshield all in a carrying case together with current calibration certificates.
Also included is the Nor 1020 software and a download cable, one set per hire. If you require extra copies, they are available at the list price.
We stock a wide range of accessories, please order what you want and only pay for what you need
Sound level meters and particularly microphones are very susceptible to damp, so should not be used outside, unless protected.

Vibration measurements using the Nor 110 Sound level meters will double as vibration meters if you can substitute an accelerometer in place of the microphone
The Nor 110 Sound Analyzer includes features that make it useful for vibration measurements
- The 1/3 octave filters extend down to 1 Hz - most sound analyzers stop at 16 Hz or higher
- Includes vibration white finger and whole body vibration weighting networks
- The time mode enables level v time measurements down to 2 ms sample periods
To calibrate key in the sensitivity given in the Calibration Certificate supplied with the accelerometer or order a B&K 4294 vibration calibrator. The B&K 4294 is the preferred method to check the accelerometer, cable(s) and meter.
The Nor 110 also has a BNC line input, so it is ideal for use with B&K 2511, 2635 or similar charge amplifiers. Alternatively a Nor 1505 accelerometer may be plugged straight into the microphone input for general purpose measurements
A B&K 4505 accelerometer is recommended for hand arm measurements - see also the GA 85W2-00 hand arm 'white finger' vibration mounting kit which should be ordered if required.
For hand arm vibration diagnostic measurements we offer the Nor 110 Hand Arm Vibration Diagnostics Kit
Hand Arm Vibration Analysis.
| Nor 110 Hand Arm Vibration Analyzer Kit | £ 36 a day * |
| Nor 110 | Multi-function Sound Analyzer - type 1 |
| B&K 4294 | Vibration Calibrator |
| B&K 4505 | Accelerometer |
| GA 85W2-00 | Hand arm vibration mounting kit |
Alternatively for triaxial vibration white finger measurements we recommend the B&K 4447 Human Vibration Analyzer or the Larson Davis HVM 100 Meter
