LSENLTY Upgraded 3-in-1 Decibel Meter for Home-PTH-9S

The 3rd Improved Version of the Noise Detector: Compared with the old version of the noise detector, we have upgraded the accuracy of the product. No need to convert any formulas, just plug it in and it will display the accurate decibel value. 3 In 1 Decibel Meter: The large-screen decibel meter uses a high-precision decibel detection chip to continuously detect noise status, temperature and humidity. Compared with traditional handheld decibel detectors, it is more suitable for home use. Portable Decibel Meter: The decibel meter is powered by a built-in 2700mAh lithium-ion battery, equipped with a 6.5ft USB charging cable, and the charging port is also included in the package. You can operate it anytime, anywhere. The battery life is 50 hours. High-precision Decibel Detector: This sound level meter uses an intelligent air semiconductor sensor to test decibel temperature and humidity values, which is more sensitive, accurate and stable than ordinary sensors.
