SC-942 Sound Level Calibrator is a device designed to calibrate and verify the accuracy of sound level meters and other acoustic measurement instruments. This generates a known and stable acoustic signal at a specific frequency and amplitude, allowing users to check and adjust their measurement equipment. They are designed to couple with the microphone of the sound level meter in a standardized way. We ensure that the calibrator is compatible with the specific type and model of sound level meter you are using. SC-942 Sound Level Calibrator provides traceability to national or international standards, ensuring that the calibration process is verifiable and meets recognized metrological standards.
