The Model 30 and Model 30-2 are high performance, yet user friendly, integrating Sound Level Meters and Real Time Frequency Analysers.

Both models meet or exceed the latest standards for compliance with worldwide Regulations and Guidelines, making them ideal for most applications.

Taking measurements is as simple as pressing the ‘record’ and then ‘stop’ buttons. The wide single dynamic span of over 110dB ensures that you never make invalid measurements that ‘Overload’ or ‘Under range’.

The Model 30 instruments simultaneously measures parameters with all Frequency and Time Weightings, this gives users the confidence to know they will always have the correct data for subsequent analysis.

Real Time Analysis allows users to measure all 10 individual 1:1 Octave Bands at the same time. This is very practical for reliable, accurate and rapid capture of variable noise levels to optimise the accurate prescription of hearing protection in industrial environments.

For environmental noise, the large memory, programmable auto repeat function and statistical LN values, combined with the optional range of Outdoor Kits, ensure the instrument is ideal for use as either a short-term or longer-term semi-permanent environmental monitor.

Noise measurements themselves are only the beginning, our outstanding and focused software packages allow users to quickly analyse and transform their data into informative report formats that save you time and effort. The Pulsar Analyser and Capture Studio software packages are supplied as standard.

Applications

Model 30 is the ideal instrument for the measurement of Industrial noise and will simultaneously measure the Leq, Lpeak and Lmax sound levels over a wide measurement range. The Analyser software can automatically optimise the instrument configuration for European Regulations.

  Precision sound level measurements
  Environmental noise measurements
  Frequency analysis of Industrial and Environmental noise
  Longer term outdoor noise measurements with optional weatherproof kits
  Real time NC curve calculations
  Impulsive noise measurement
  Optional reverberation time measurement in 1:1 Octave Bands

Measurements

Model 30 Sound Level Meters simultaneously measure all functions and frequency weightings, as well as additional parameters depending upon the configuration of the instrument.

For example, the instrument can be configured to store the Leq, displayed as LT, in dB(A), dB(C) and dB(Z) with the Maximum and Minimum values stored in all three frequency weightings as well as all three Time Weightings. Peak Sound Pressure will also be stored.

In 1:1 Octave Band Mode, the Model 30 will store the Leq (LT) in each Octave Band, the overall Leq level in dB(A), dB(C) and dB(Z) as well as the overall Peak Sound Pressure Level as well as in each 1:1 Octave Band.

Model 30 Sound Level Meters can be upgraded with additional functions such as Reverberation Time Calculation which meets ISO 3382:1997, ISO 354:1985 and ISO 140:1998. This makes the Model 30 ideal for use in building regulation measurement systems.

Data Storage

Users can choose how many parameters are stored in the memory of the instrument, which then determines the maximum time the instrument can measure before the memory is full.

Functions F1, F2 and F3 can be defined by the user to suit the measurement situation and can be chosen from any of the available measurement parameters.

Software

Pulsar Model 30 instruments are supplied with Analyser software that allows stored measurements to be downloaded to a PC for reporting and further analysis.

The Capture Studio software facilitates the Graphical ‘Live Display’ of up to three parameters if the Model 30 is connected to your PC. Post-processing allows detailed 3-Dimensional Frequency Analysis Modelling to be performed using downloaded measurement data.

This software is compatible with Windows 9x/Me/2000/NT/XP and Vista.

Measurement Kits

Instruments can be supplied as a complete measurement kit to ensure you have all of the accessories necessary to perform your noise survey.

The Noise Measurement kits include Sound Level Meter, Acoustic Calibrator, Windshield, Hard Attache Case, Wrist Strap, Carry Pouch, Software, Operating Manuals, Certificates of Calibration, Download Cable and Batteries.

Outdoor Measurement Kits

To allow the Model 30 Sound Level Meters to be used outdoors, two weatherproof measurement kits are available. The standard WK1 kit uses the microphone, preamplifier and cable from the Sound Level Meter to make a simple, lightweight system suitable for overnight and occasional use.

For longer term measurements, the WK2 kit uses a complete integral outdoor microphone assembly, which has a superior degree of weather protection for the microphone capsule.
