Quest offers a wide variety of Octave Band Filter Sets which feature manual and automatic sequencing. With these unique filter sets, the capabilities of many Quest sound level meters can be expanded to include octave band analysis.



The OB-300 combination 1/3-1/1 Octave Band Filter Set gives a choice of measuring 33 one-third octave bands or selecting standard 1/1 octave band measurements. The filter set will automatically or manually sequence through each octave or third octave band and display the measured level on the sound level meter.

The OB-100 has the same automatic and manual features of the OB-300 except that measurements are made in full-octave bands only.

The OB-50 provides nine octave bands from 31.5 Hz to 8 kHz.

The light-weight filters adapt easily to modular design of Quest's Model 1700, 1800, 1900, 2700, 2800 and 2900 sound level meters
