Name: Extech 407780A Sound Level Datalogger with NIST Calibration
SKU: 239955

The Extech 407780A Integrating Sound Level Meter with USB is a comprehensive tool for accurate sound level monitoring and data analysis. Designed for both industrial and environmental applications, it offers advanced measurement capabilities such as Leq (Equivalent Continuous Sound Level) and SEL (Sound Exposure Level), enabling professionals to evaluate cumulative sound exposure with precision.

Featuring a 4-digit LCD with an analog bargraph, this meter delivers real-time feedback across a wide 100dB range. Users can select between A and C frequency weightings and adjust response settings to Impulse, Fast, or Slow modes to suit different environments. A built-in datalogging function stores up to 32,000 readings, supported by a real-time clock and USB connectivity for streamlined data transfers to PC using the included Windows software.

The Extech 407780A is equipped with outputs for analog signal monitoring and alarm triggering, making it compatible with external devices such as frequency analyzers and sound alarms. With programmable integrating time and tripod mounting, it's a reliable solution for extended, hands-free monitoring.
