This meter combines advanced features such as Leq and SEL measurements, a built-in datalogger, and a PC interface to provide a complete solution for sound level analysis and data logging.
The Extech 407780A is an integrating sound level meter that allows for the measurement of Leq (Equivalent Continuous Sound Level) and SEL (Sound Exposure Level). These measurements provide valuable insights into the overall sound level and the cumulative exposure to sound over time. With the A and C frequency weighting options, you can select the appropriate weighting for your specific measurement requirements.
The meter features a built-in datalogger, capable of recording up to 32,000 records. This allows for long-term monitoring and data collection without the need for constant manual recording. The recorded data can be easily accessed and analyzed using the PC interface, providing a convenient way to review and interpret the logged information.
The 4-digit multifunction LCD display of the Extech 407780A provides clear and comprehensive readings. It includes an analog bargraph and a digital reading for programming integration times, allowing you to customize the measurement parameters according to your specific needs. The meter also offers impulse, fast, and slow response settings, giving you flexibility in capturing different sound characteristics.
Additionally, the meter benefits from alarm features, which can be set to trigger when certain sound level thresholds are exceeded. This allows for immediate notification of sound level breaches, ensuring prompt action can be taken when necessary.
