Today, there is a need to know just how loud your surroundings really are. The CHECK MATES decibel meters are inexpensive tools everybody should own. The Galaxy Audio CM-140 and Galaxy Audio CM-170 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 the Galaxy Audio CM-140 and all other 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...
Over time, all SPL meters lose their calibration. The Galaxy Audio CM-C200 is a sound pressure level (SPL) meter calibrator. The CM-C200 meets IEC 60942 2003 Class 2 and ANSI S1.40-1984 standards. The CM-C200 can calibrate 1", 1/2" and 1/4" microphone capsules at 94dB and 114dB.
The calibrator is designed to calibrate SPL Meters with a microphone diameter of 1/4", 1/2" and 1". The CM-C200 will work with any of the CheckMate SPL Meters and many other brands. The CM-C200 has a test tone at 1kHz at both 94dB and 114dB. The CM-C200 includes 2 adaptors a protective zipper pouch and manual.
