Galaxy Audio CM-170 Type II SPL Meter w/USB Cable

The CM-170 is the latest in the line of Galaxy Audio SPL Meters. The CM-170 is similar to the CM-160 model, except that it has data logging with clock feature, fast/slow time weighting, and electronic calibration. The CM-170 comes complete with a carry case, windscreen, USB cable, and software for computer.

Today, there is a need to know just how loud your surroundings really are. The CM-170 is an affordable IEC 61672-1 Type II SPL meter that competes with some of the best SPL meters on the market. The CHECK MATES are inexpensive tools that everybody working in loud environments should own, including working musicians, DJs, police departments, and sound contractors. 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.
