Model Galaxy CM-140 -Sound Level Meter

The CM-140 conforms to IEC Class 2/ANSI Type 2 standards for General Purpose sound level meters. We also provide value added services to ensure the accuracy of the meter:

1. Verified Models: We check each unit using a Type I calibrator and set the calibration adjustment as necessary to ensure that the unit is as accurate as possible when you receive it. The Verified models include a data sheet that indicates the calibration performance and meteorological conditions under which the calibration was performed.
2. Verified+ Models: In addition to the calibration check performed with the Verified models, we also measure the on-axis and random incidence performance of each meter in its A-Weighting and C-Weighting modes. A report is included with each unit which compares the freefield performance of the meter with ANSI tolerances. We also include the frequency response data on a USB thumbdrive (FRD format); the data can be used as a correction curve to obtain a flat sound level when used with appropriate PC software.

All meters will be shipped with the following:

• Galaxy CM-140 Sound Level meter
• Windscreen, manual and 9V battery
• Calibration report
• (Verified+ units only): USB thumbdrive with frequency response data (.FRD format)
