Sound level calibrator Center 326 (Code: 7002)

Sound level calibrator Center 326 

The Sound calibrator centertek 326 is used to adjust sound pressure meters according to IEC 942 class 2. This device allows calibrating the complete measurement chain.  With such device you can perform absolute SPL measurements with a microphone and a PC based audio analyzer like our measurement systems Akulap or any sound level meter.

There are many applications, where a class 2 calibrator is sufficient. The Center 326 is worldwide accepted as a reliable tool in this class. It is sold for more then 15years.

This calibrator is regulated, which means that a reference microphone constantly monitors and controls the sound level. As a result, the size of the pressure chamber or a non-100% sealing microphone has no effect.
