CAL300 class 1 acoustic calibrator

Standard noise source at high stability in level and in frequency, the CL300 acoustic calibrator emits a nominal acoustic pressure level of 94 dB or 114 dB at a frequency of 1000 Hz. It corresponds to class 1 of standards NF EN 60942: 2003 and IEC 60942: 2003

Designed to remain compatible with microphones of different diameters, it is supplied with an adapter ring for a microphone of ½ inch diameter. .
