SV 30 & SV 31 Acoustic Calibrators
|
 |
OVERVIEW
The SV 30A - two levels and the SV 31 - one level acoustic calibrators
are the State of the Art instruments. The design of both calibrators is
based on the dedicated 1/2” condenser microphone and microprocessor
controlled signal source including digital static pressure and
temperature compensation. These both features assure excellent stability
of the calibration levels and their frequency.
The SV 30A and SV 31 calibrators offer exceptional price versus
performance ratio on the world market of sound measurements
