VOLTCRAFT SLC-100 Sound Level Calibrator

The Voltcraft SLC-100 sound level calibrator allows the simple alignment of sound level measuring devices and for testing measuring accuracy. The calibrator generates a 1kHz sinusoidal sound signal with a switchable sound level of 94 or 114dB. Microphones with a diameter of 12.7mm (0.5in) can be inserted in the calibration chamber. The specified accuracies are obtained at an atmospheric pressure of 1013hPa, an ambient temperature of 23°C and an air humidity of 65%RH. Supplied with 1 x 9V battery, case, and user manual.
