Featuring a high-sensitivity probe for swift responsiveness during measurements, its microphone design employs a metal through-hole with a windproof sponge ball, ensuring dual-layered protection against damage from accidental drops. This instrument offers multiple measurement modes, including minimum and maximum value measurement, reflecting real-time results and providing users with the current measurement’s maximum or minimum noise value. Additionally, users have the option to select between automatic or manual shutdown, with an automatic shutdown feature adjustable for up to 120 minutes, enhancing convenience by automatically turning off the instrument in the absence of user activity within the specified time frame.
