Sound Calibrator [AC-300]

The 3M AcoustiCal AC-300 is a precision calibrator designed to help you accurately field calibrate your sound level meters and noise dosimeters. Designed for ANSI and IEC Class/Type 1 meters, the AC-300 makes it easy to calibrate your instrument before and after each series of measurements. It produces two signals, 250 Hz or 1,000 Hz at a sound pressure level of 114 dB, allowing for selection of the mode that best fits your application. A quick and easy process, users simply insert the microphone of the instrument into the AC-300 calibrator, select the signal from its simple one-button keypad, and calibrate.
