Galaxy Audio CM130 Sound Pressure Level Meter
Today, there is a need to know just how loud your surroundings really are. The CHECK MATES are inexpensive tools everybody should own. Windscreen and battery are included with each of the CHECK MATE models.
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. We have expanded our line from one CHECK MATE SPL Meter to four products in the category. We have sold thousands of units to working musicians, DJs, police departments, sound contractors, racetracks, etc...
