• Wide 107 dB linearity range allows sound level measurements from 30 to 130 dB without range switching

• Easy measurement of sound level (Lp). Equivalent continuous sound level (Leq),
maximum sound level (Lmax). Sound exposure level (Z, E). And peak sound level (Lcpeak)

• Manual store function and capability to transfer data to a computer via optional USB adapter cable

• 9 hours operation on two AAA (IEC R03) alkaline batteries

Rion’s NL-42 Class 2 Sound Level Meter allows for measurements from 20 to 8000Hz in a single hand held portable Unit. It combines cutting edge technology with excellent quality and unrivalled ease of use.

Key Features Include:

· Ease of use – main functions on dedicated, backlit keys

· Superb high-contrast backlit TFT-LCD colour display

· Allows simultaneous Channel and Sub-Channel measurements

· The unit (except for the microphone) is water-resistant, which means that it is unaffected by sudden rain showers

· Massive storage capacity using text files stored to Compact Flash memory cards

· Flexible and simple PC connectivity (CF card and USB Virtual Disk)

· Exceptional battery life

NL-42 Complies with the following standards for Sound Level Measurement

IEC 61672-1: 2002 Class 2

ANSI S1.4-1983 Type 2

ANSI S1.4A-1985 Type 2

ANSI S1.43-1997 Type 2

JISC 1509-1: 2005 Class 2

Optional Program Cards allow for easy and convenient expansion of functionality

NX-42RT

By adding a program to the NL-42, octave band and 1/3 octave band real-time analysis can be realized. Saved analysis results can be loaded and shown in an overlay graph display together with current analysis data. NC curve graph display and NC value calculation/display are also possible.

NX-42WR

Makes it possible to measure sound pressure levels together with sound pressure waveforms during frequency analysis. This allows you to listen to specific events. Recorded data can be played back on the PC and used for frequency analysis

NX-42FT

This program card adds FFT analysis capability to NL-42, with an analysis frequency range of 8kHz and 8000 analysis lines. Saved analysis results can be loaded and shown in an overlay graph display together with current analysis data. Maximum zoon ratio is x40 and the top list screen can show up to 20 lines

Optional Program Cards

NX-28WR

Makes it possible to measure sound pressure levels together with sound pressure waveforms during frequency analysis. This allows you to listen to specific events. You can also reanalyse recorded sound.

NX-28FT

This program card adds FFT analysis capability to NA-28, with an analysis frequency range of 20kHz and 8000 analysis lines.

NX-28BA

This program card is used for simple and easy measurement of airborne and floor impact sound insulation of buildings and reverberation time. Data is stored as text files. When used in conjunction with waveform recording card NX-28WR, sound waveforms during measurement can be recorded simultaneously.

Rion NC-74 Sound Calibrator

The Rion NC-74 Sound calibrator generates a constant sound pressure of 94 dB at 1kHz.

The Rion NC-74 is designed to be a compact and lightweight unit which requires no atmospheric pressure compensation.

This is done by incorporating a sensor which detects the atmospheric pressure which is in turn detected by the CPU which controls the signal amplitude. This eliminates the need for any pressure compensation.

The Rion NC-74 Sound Calibrator is suitable for 1” and ½“ microphones

Rion NC-74 Sound Calibrator complies with the IEC 60942:2003(JIS C 1515:2004) Class LS/C

Features:

* Allows for calibration with accuracy of + 0.3 dB

* Usable in wide temperature and humidity range.

* Usable as a standard sound source in laboratories or as a calibration sound source for sound level meters on site.

Additional Information:

• Item Code: NC74
