Review on High-Precision Sound Decibel Calibrator for Accurate Calibration Measurements by Kevin Griffin

Industrial and Scientific enthusiasts beware! This Sound Decibel Calibrator Calibration Meter is an absolute letdown. I purchased this instrument for on-site noise level measurement for my industrial work. To my disappointment, it's inaccurate readings made it unusable, making it a big waste of money. However, it's compact size is a plus point, but it's poor quality mechanics make it an unreliable tool for any professional work.
