Extech 407760 USB Sound Level Datalogger
The Extech 407760 USB Sound Level Datalogger is a compact, professional-grade device that logs sound levels over time and transfers data to a PC via USB. It offers high accuracy and flexible configuration for long-term noise monitoring.
Description
This instrument is capable of measuring sound pressure levels in the approximate range of 30 dB to 130 dB, with A and C frequency weightings and selectable response times (Fast/Slow) to suit different acoustic measurement scenarios.
It features a built-in data-logger that can store up to 129,920 readings, each stamped with date and time, and with configurable sampling intervals via the supplied Windows software.
For connectivity, it has a USB interface that allows direct connection to a PC for configuring logging parameters (such as start mode, sample rate, alarm limits) and downloading logged data for export, graphing or analysis.
The instrument meets ANSI/IEC Class 2 standards (for sound level meters) with a basic accuracy of around ±1.4 dB.
It is supplied ready for field use with accessories such as a windscreen, USB cable and extension, tripod mount, and long-life lithium battery.
In short: the 407760 is well-suited for professionals and technicians who need to carry out noise level surveys, continuous monitoring, or compliance measurements where capturing time-history data is important.
