We offer calibration services for acoustic measuring instruments at the highest technical level. In addition to acoustic measuring instruments, we can also calibrate DAkkS-certified audiometric calibration devices used in medical engineering—such as artificial mastoids and “ear simulators”—and trace them back to the national standard.
You determine the calibration interval. This depends on the application of the sensors. We would be happy to advise you on the correct interval for your device!
