CHECK MATE CM-150 Sound Level Meter

The Galaxy Audio CM-150 Decibel Meter can accurately register up to 130dB. The CHECK MATE series SPL (Sound Pressure Level) meters, first introduced in early 2003, allow musicians, sound contractors, and others to measure SPL in decibels (dB). A decibel is defined as the unit for measuring relative loudness of a sound. The CM-150 meets the same IEC 651 Type 2 standards of SPL meters that cost 5 times as much or more. Windscreen and battery are included with each of the CHECK MATE models.
