1. High-precision measurement - the digital sound level meter uses high-precision sensors, which can accurately measure noise, sound pressure and other related parameters. At the same time, it also has high stability and anti-interference ability, which overcomes the shortcomings of traditional noise detection methods.2. Clear display - the noise meter is equipped with a high-definition LCD display, which can intuitively display the test results, allowing users to easily understand the environmental noise level. At the same time, it can also record the maximum, minimum and average noise values, and has a good data storage function.3. Multiple test modes - the digital sound level meter has multiple test modes, such as fast response, slow response, maximum hold, etc., which can adapt to different environmental testing needs.4. Portable and easy to carry - the digital sound level meter adopts a light and portable shape design, which is easy to carry and use. The body is small and can be put into the pocket, which is convenient for testing at any time.5. A large number of applications - the noise meter can be widely used in industrial fields, safety monitoring, traffic noise monitoring, environmental protection testing and other fields, providing accurate noise detection and monitoring services for relevant departments and enterprises.
