Acoustic Calibrators

The high reliability of electronic measuring instruments such as sound level meters enables you to make accurate measurements after a simple check with one of our acoustic calibrators. In many cases this check is also carried out after each measurement to validate the results. To make sure an instrument is working correctly, more comprehensive checks are required periodically making the portable acoustic calibrators an excellent choice for making highly accurate, in-field calibration of your measuring instrument.

TYPE 4226

Multifunction acoustic calibrator
Multifunction Acoustic Calibrator Type 4226 enables simulated free-field calibration of microphones, sound level meters and other related instruments in compliance with standards EN/IEC 60942 / ANSI S1.40.
TYPE 4229

Hydrophone Calibrator
Hydrophone Calibrator Type 4229 is a precision, high-quality sound pressure source. It delivers an easy method to calibrate sound measuring systems by employing a B&K Hydrophones in air.
TYPE 5008

Polarization Voltage Calibration Unit
Type 5008 is a differential DC buffer intended to act as a buffer for high-impedance microphone polarization voltage, allowing the microphone polarization voltage to be measured using a common DC voltmeter.
TYPE 3541-A

Sound intensity calibrator
Our sound intensity calibrator enables calibration of sound intensity measuring instruments by using a coupler designed especially for the purpose.
