Larson Davis LxT-QPR Noise Level Meter - Class 1 Noise Level Meter and Real-time Noise Analyzer for Shooting Ranges/Tracks Inspection

Larson Davis LxT-QPR Noise Level Meter - The LD LxT-QPR is a compact, user-friendly, portable handheld device for measuring the noise of handguns and firearms, to check their attenuation. It can be used for the development of shooting ranges, sports facilities, training and competition tracks, as well as for urban or industrial environmental noise level measurements. The device is equipped with a built-in - directional - microphone primarily specified for detecting noises generated by handguns.

The Larson Davis LxT-QPR noise level meter features additional user-friendly attributes such as a backlit graphical display and a comfortable, ergonomic keyboard. Furthermore, the Windows-based PC software assists in setting up the device, downloading data, evaluating data, and exporting data to spreadsheet programs.
