Calibration Systems and Calibrators
The use of sound calibrators dates back to the days when it was easier to design a stable sound calibrator than a stable sound level meter. Today, sound measuring instruments, in general, are as stable as the sound calibrators.
However, measuring microphones are very delicate devices designed to fulfil very rigid specifications. This makes them vulnerable and subject to damage unless care is taken.
One may therefore say that a calibrator is just as much a verification of proper operation as it is a device for re-adjustment of sensitivity of sound measuring instruments.
Scantek offers calibrators from various manufacturers for everyday use.
Scantek also offers a complete calibration system from Norsonic is available for precision, laboratory-grade calibration.
