Larson Davis Noise Dosimeters
EON rents the Larson Davis Spark 705 Noise Dosimeters because they are easy to use and completely sealed in an extruded metal housing, with no controls or display to tamper with or damage. The basic model Spark 705 is configured by the user with a Windows PC to start automatically and gather noise exposure data at the intervals you select, unobtrusively, time after time. Capable of storing up to fifty separate tests in a memory that can never be accidentally erased - even with the battery removed - the 705 creates a concise, one-page report with all your compliance data and a clear graphical picture of your noise exposure profile.
