Flir Extech 407860 Meter Specification

The Flir Extech 407860 is a sophisticated integrating sound level meter designed for precise noise measurement applications. It features a wide dynamic range from 30 to 130 dB, allowing it to accurately capture both low-level ambient sounds and high-intensity noise. The device incorporates both A and C frequency weighting, enabling it to simulate human ear response and provide flat response measurements for a variety of acoustic analyses.

The meter is equipped with an integrating feature that calculates sound level over time, providing an equivalent continuous noise level (Leq) reading. This makes it particularly useful for environments where noise fluctuates, allowing for comprehensive noise assessment over extended periods. Its digital display offers clear readouts, and the device supports data logging capabilities, enabling users to record and later analyze sound level data on a connected PC via USB or RS-232 interface.

With a robust design, the 407860 is suitable for both indoor and outdoor use, featuring a windscreen to minimize measurement distortion in breezy conditions. An included tripod mount enhances stability for long-term monitoring. The meter adheres to ANSI and IEC 61672-1 Type 2 standards for accuracy, ensuring reliable performance across various industrial, environmental, and occupational noise monitoring scenarios. The device is powered by standard batteries, providing portability for fieldwork, and includes an AC adapter for extended sessions. With user-friendly controls and a comprehensive manual, the Flir Extech 407860 is an essential tool for professionals requiring detailed sound analysis and noise compliance testing.
