Nor131 / Nor132 Sound Level Meters

Nor131/ Nor132 Sound Level Meters Nor131 and Nor132 are designed and manufactured to the latest sound level meter standards and comprises two products. The Nor131 is a Class 1 ( precision) instrument whilst the Nor132 is designed in accordance with the less accurate Class 2 requirements. Both meters offer the same features with exception of the detachable preamplifier which is only available on the Nor131 version. Applications: • Noise hazards in the workplace • Prescription of hearing protection • Environmental noise investigations • Product noise testing • General purpose sound level meter Features: • Single measurement range • Extremely simple operation • Parallel LAeq and LCpeak • Real-time octaves • Large internal memory • Clock synchronized measurements • Single measurement range • USB interface • Allows use of microphone extension cable ( Nor131 only) • Large back-lighted display • Complies to IEC and ANSI standard • 1/ 1 octave ( optional) • 1/ 3 octave ( optional) • Statistical analysis ( optional) • Level versus time ( optional) Nor131/ Nor132 Description Easy to use - just push the START key and measure! No need to worry about gain setting as the instrument covers the entire range from 20-140 dB in one single span. When the measurement stops, the auto-store feature writes your measurement in the non-volatile memory. The Nor130 Series of SLM’ s uses the latest available digital technology to give the operator a clear view of the noise climate. The main operations are performed through dedicated front panel keys in order to give instant access to all required functions during the measurement. No need to pre-select required measurement function before starting the investigation. Simply press the NETW-key to swap between the A– and C– weighting networks, and press the FUNC-key to scroll through all the measured functions. The high resolution backlit graphical display presents all results clearly. The graphical screen contains a bargraph with the instantaneous SPL level plus the numerical value of the selected functions for both weighting networks. Date, time and the instrument status are displayed as well. Quatro detector The Quatro detector in the instrument is capable of detecting both the RMS– and the Peak– levels from two weighting networks simultaneously! Hence, the Nor130 Series offer industrial hygiene specialists the LAeq, LCeq, LApeak, and LCpeak from one single measurement. Large memory Measurement results may be stored in the 5 MByte internal memory. This memory is of the ” flash” type that will retain the information without a power supply. The memory typically holds all measured functions from up to 10, 000 individual measurements. If both the optional features, octave analysis ( Option 1) and statistical indicies ( Option 2) , are installed the memory will hold 2, 500 sets of results. USB interface Remote control of the instrument is possible via the state-of-the-art USB interface. All features may be controlled, and all measured results may be read-out. By use of the Norsonic NorXfer software ( ordered separately) , data downloading is completed in a few keystrokes in a Windows Explorer environment. Occupational hygiene The Nor130 Series is ideal for noise deafness risk assessments under the EU Physical Agents ( Noise) Directive. It measures all required functions, and presents the results both during and after the measurement period. The LAeq, t and LCpeak values are provided to allow the LEP, d and peak action levels to be Determined from quick and simple measurements at each workstation. Where exceedences are detected the LCeq– LAeq value is available to allow the HML method of hearing protector to be specified. For a more detailed analysis, the instruments may be upgraded with 1/ 1- or 1/ 3-octave real-time frequency analysis ( Option 1 and 4) . The resulting frequency spectrum is available at the same time as the initial measurement and gives the information necessary to both specify noise control measures and for the correct prescription of personal hearing protection. Environmental noise assessments By adding the statistical LN function ( option 2) the instrument will also provide the dB values in terms of the L5, L10, L50 , L90 etc that are required to determine the impact of noise in the community. These measurements often require long term noise monitoring. With the clock synchronized automatic storage facility in the Nor130 series, repeated measurements may be performed with the results automatically stored to allow these long term measurements to be made, yet preserving the temporal data on the dispertion of the levels. By taking, for example, 5 minutes measurements on repeat store, the Nor130 instruments will produce 288 measurement per 24 hour period. These measurement files are easily downloaded to a PC using the NorXfer software which will additionally convert all these files into one single Excel-file containing an overview of all the measured data for the entire 24 hour period. An enhanced solution is also provided by adding the level vs. time option ( option3) . This allows a more detailed analysis with period resolution selectable from 1 sec. Each period in the profile consist of LAeq, LAmax and LCpeak ( or LZpeak) . In addition is the overall measurement result for the entire level vs time period reported. This equals to a “ normal” measurement done with the basic sound level meter. Hence, the user may get a high resolution report for each period with LAeq, LAmax, LCpeak and an overall measurement report for the same parameters in addition to the other parameters measured in the basic version and optionally 8 statistical values and frequency analysis ( 1/ 1 or 1/ 3 octave band real time analysis) . " Firecracker" noise measurement The Nor131 and Nor132 Sound Lever Meters with a suitable prepolarized microphone are very good choices for the measurement of firecracker noise. This type of noise is characterized by very high peak levels, but with a suitable 1/ 4" microphone connected to the meter through the use of an adapter, one can accurately measure levels up to 174dB ( the meters can display levels to at least 180dB) .
