SOUND LEVEL METER The SoundPro SE / DL series provides advanced sound level monitoring and comprehensive data analysis. Available in Class 1 and Class 2 models, these instruments feature large screen displays that enable real-time frequency analysis, and data storing capabilities that make it easy to post-process and evaluate workplace noise levels.  The aerodynamic shape of the SoundPro is specifically designed to minimize disturbance to the sound fields being measured. From industrial and task noise sampling to hearing conservation, the SoundPro SE / DL series provides accuracy, ease-of-use and, if needed, data for professional follow-through. Features such as a menu driven user interface, quick keypad calibration, removable SD memory card and optional QuestSuite™ Professional II software (Call for details) allow users to simply and reliably perform advanced sound analysis. Typical Applications Include: Occupational noise evaluations Environmental noise assessments Noise ordinance enforcement and legal metrology General sound and frequency analysis Vehicle noise evaluations Quality control and process measurements Building acoustics Mobile equipment evaluations   Features of the SoundPro Meters:  ANSI & IEC standards compliant Available in Class 1 Precision or CLass 2 General Purpose models Two "virtual" sound level meters running simultaneously Concurrent A-weighted and C-weighted measurements Programmable and level-triggered start and stop A,C,Z and F (Flat) frequency weighting Fast, slow, and IEC Impulse time response Selectable thresholds 10 dB - 140 dB 3, 4, 5, 6 dB exchange rates Luminescent keypad and backlit display SD memory card slot USB communications port and serial RS-232 output Multilingual display (English, French, Spanish, German, Italian, Portuguese) Time history data logging with 1 second to 60 minute intervals (DL only) Back erase function Noise dose calculation / dosimetry functio
