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. Windscreen and protective case are included with 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...

The CM-170 is the latest in the line of Galaxy Audio SPL Meters. The CM-170 is similar to our 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.

  • Freq. Range: 20Hz - 8kHz
  • Freq. Weighting: A/C
  • Fast/Slow Time Weighting
  • Data Logging with Clock
  • USB Mini Interface
  • Includes Software and USB Cable for Charging
  • IEC 61672-1 Type II
  • Range 30 - 130dB
  • Accuracy ± 1.4dB
  • Electronic Calibration

CM-C200

Over time, all SPL meters lose their calibration. The CM-C200 is an 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.

  • Accurate and simple to use
  • Calibration levels of 94dB and 114dB at 1kHz
  • Fits 1", 1/2" and 1/4" diameter microphones
  • Conforms to IEC 60942 2003 Class 2 and ANSI S1.40-1984 
  • Weight: approx 0.41lbs (186.4g) (including battery)
