- Model Quantifier 95 and 96 - Handheld octave band sound meter


The Model 95 (Class 1) and Model 96 (Class 2) have 1:1 and 1:3 Octave Band Filters for the identification and subsequent analysis and control of noise sources that may require tonal analysis, making them a cost-effective, yet fully compliant instrument.

This simple to use sound meter provides an ideal solution for general, industrial and environmental noise measurements. All the measurement functions comply with worldwide standards, noise regulations and guidelines. These include the measurement of Lmax, Lmin, Leq and five Ln values including L10, L90 and L95.

The Quantifier stores the Time History which is often crucial when measuring environmental noise. Data logging of the required measurement parameters is standard and up to 12 days of 1 second Time History data can be stored. This can then be analysed using Pulsar's Analyser software to discover specific noise sources and take the necessary action.
