Description
PCE Instruments Class 2 Decibel Meter Calibrator (PCE-SC 43) is a reliable device for verifying and adjusting sound level meters. It features three selectable sound pressure levels—94 dB, 104 dB, and 114 dB—allowing for precise calibration in various noise measurement applications.
Its ±0.4 dB accuracy makes it an essential tool for checking the precision of sound-measuring devices. Designed for extended use, it offers up to 50 hours of battery life and an automatic shut-off function to conserve power during periods of inactivity.
