The Frequency Analysis module included in all our 2250 Sound Level Meters, providing real-time analysis of the 1/1- and 1/3-octave filter bands over a wide frequency range, and over a dynamic range from the noise floor in each individual band to a maximum level of 140 dB.

Spectral data can be measured for five different parameters (Leq, LFmax, LFmin, LSmax, LSmin). You can select which frequency weight (A,C or Z) during the measurement setup. In addition, instantaneous values are available for display. Two spectra, for example, a minimum and maximum spectrum, can be superimposed on the display.

One measurement is all you need
A single, wide dynamic range, combined with simultaneous measurement of RMS and peak levels with different frequency and time weightings, you can gather all information in one go.

Large display for more accurate measurements
Observe measurements from a distance, avoiding acoustic reflections from your body which would bias the measurement.

Everything in one glance without clutter
The colour display provides spectral data both graphically and in tabular form, clearly providing a wealth of data and measurement quality information in an easy-to-navigate way.
