 Today, there is a need to know just how loud your surroundings really are. The CHECK MATES are inexpensive tools everybody should own. The
CM-140 and CM-150 meet 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.
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...
