SPL Meter Includes ELA

The Model 831 debuts as a handheld sound pressure level (SPL) meter with exceedance-based logging analysis (ELA) for community noise assessment. Sporting a small, lightweight ergonomic design, the meter provides real-time 1/1 and 1/3 octave spectra measurement and specifies a 120-dB dynamic range. Ten customizable markers are provided to annotate history data. An audio and voice recording feature with replay is supported with up to 2 GB of on-board memory and more via an optional USB 2.0 data stick. For unattended noise monitoring, event-based logging routines process data and provide time/date, duration, average and max/min sound levels, frequency spectra, time history records of selected sound levels, and recordings for each event. Additionally, accessories are available including software, sound level calibrators, microphones, weatherproof enclosures, and a variety of tripods and tilt-down poles. LARSON DAVIS INC., Provo, UT.
