Type 2239A integrating sound level meter.

Type 2239 A is a Class 1 sound level meter designed for measurements of noise. The instrument has two parallel, independently weighted detectors that enables it to display RMS and Peak readings simultaneously.

2239 A can store up to 40 measurements, and if the time is preset, storage is automatic.

A large LCD screen displays measurements and includes a quasi-analog bar showing the current sound pressure level.

All data from Type 2239A can be read and post-processed by Brüel&Kjær's environmental software packages. Type 7815 allows storage, management and inspection of data.

Evaluator™ Type 7820/21 is dedicated to handling environmental-noise measurements and calculations of rating levels.
