The Extech 407730-NIST Sound Level Meter is a reliable and accurate tool for measuring sound levels. This meter is designed for professionals in various industries, including environmental monitoring, occupational safety, and audio engineering.

The Extech 407730 measures sound levels ranging from 40 to 130dB with an accuracy of 2dB, providing precise and reliable readings. It offers a digital display with a 0.1dB resolution, allowing for detailed and easy-to-read measurements. Additionally, the meter features a fast responding analog bar graph, providing a visual representation of sound level changes over time.

To suit different measurement requirements, users can choose between A or C weighting. The A-weighting is commonly used for general sound level measurements, while the C-weighting is often used for evaluating low-frequency noise. This flexibility allows for accurate and tailored measurements in various environments.

The Max Hold function captures and displays the highest sound level recorded during a measurement session. This feature is particularly useful when monitoring sound levels in fluctuating environments, ensuring that the peak readings are captured and analyzed.

The Extech 407730 Sound Level Meter is designed for ease of use and reliability. It offers a compact and handheld design, making it portable and convenient for on-site measurements. The meter is powered by batteries for flexibility in use. It includes NIST Certification.
