The Extech 407750 Sound Level Meter with PC Interface is a versatile and advanced instrument for accurate sound level measurements. This meter is designed to meet the needs of professionals in various industries, including environmental monitoring, occupational safety, and acoustic analysis.

The Extech 407750 features a large backlit display, providing clear visibility and ease of reading even in low-light conditions. This ensures that you can easily view and analyze the sound level measurements, enhancing usability and convenience.

Equipped with a PC interface, the meter allows for seamless connectivity to external devices such as computers. This enables you to transfer and analyze the measured data directly on your PC, facilitating data management and further analysis.

The meter includes a background sound absorber, which is particularly useful in environments with high ambient noise levels. This feature helps minimize the interference of surrounding noises, ensuring accurate and reliable measurements.

The Extech 407750 offers both A and C weighting options, allowing you to select the appropriate frequency weighting for your specific measurement requirements. The A-weighting is commonly used for general sound level measurements, while the C-weighting is often used for evaluating low-frequency noise.

The meter provides options for fast and slow response times, allowing you to choose the response time that best suits your application. The fast response time captures rapid sound level changes, while the slow response time provides a more averaged reading over time.

Additional features of the Extech 407750 include Min/Max functionality, which allows you to track and record the minimum and maximum sound levels over a specific period. This feature is particularly useful for identifying peak noise levels.

The meter also offers analog AC/DC outputs, providing the option to connect the meter to a recorder or data logger. This allows for continuous monitoring and recording of sound level data for further analysis.
