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, CM-150 and CM-160 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. Thousands of Galaxy SPL meters have been sold to working musicians, DJ's, police forces, sound contractors, racetracks around the world.
The CM-160 is the latest in the line of Galaxy Audio SPL Meters. The CM-160 is similar to the CM-150 model, except that it has an internal hard drive, which records the SPL and allows it to be transferred to a computer at a later time. The CM-160 comes complete with a carry case, windscreen, USB cable, and software for computer.
