Larson Davis LxT N/Forcer Sound Level Meter - Class 1 Sound Level Meter and Real-time Sound Analyzer for Regulatory Inspections

Larson Davis LxT N/Forcer Sound Level Meter - The LD LxT N/Forcer device has been specifically developed to meet the requirements for environmental noise levels (e.g. events, concerts) and industrial noise emission measurements. The instrument combines the capabilities of a sound level meter data collector and a real-time sound analyzer in a compact, robust, user-friendly handheld device. Its special features include: replayable audio and sound recording, real-time 1/1 and 1/3 octave analysis, and dosimeter recording function.

The backlit, high-contrast graphical display and keyboard make the device easier to operate, while the Windows-based PC software assists in setting up and remotely controlling the instrument (optional), as well as downloading, evaluating, and exporting data to spreadsheet programs (via standard USB connection).
