It generates a stable 114 dB sound pressure level at selectable frequencies of 250 Hz or 1,000 Hz, providing reliable field calibration for Class 1 and many Class 2 measurement systems. Designed for simple one-button operation, the AC-300 offers fast, repeatable calibrations in a compact, portable package. Its rugged construction, automatic power-off function, and long battery life make it ideal for laboratory, industrial hygiene, environmental noise, and occupational health applications.
