Svantek SV30A class 1 (Code: 7001)

The SV 30A - two levels acoustic calibrator and the SV 31 - one
level acoustic calibrator 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
SV 30A SV 31
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.
