Acoustic Calibrator for Sound Level Meters

声级计用声校准器

Every reputable noise survey starts and ends with a calibration check, and this pocket source is what field teams carry for it. It produces 94 dB and 114 dB at 1 kHz with ±0.2 dB level accuracy to IEC 60942 Class 1. A 250 Hz tone is optional; adapters cover 1/4-inch and 1-inch microphones as well as 1/2-inch.
