Wall-Mountable Decibel Meter Sound Level Reader — Classroom Noise Meter with Humidity & Temperature

Features a high-definition, backlit LCD for easy reading day or night. Unlike handheld sound level meters, this premium wall-mountable dB meter installs quickly and is built for continuous monitoring. Use it anywhere in your space: it mounts to the wall and includes a 10ft power cord, sits securely on tables thanks to a flat-bottomed design, or runs unplugged for hours on its internal 2000MaH battery. Also doubles as a home theater SPL meter by the TV or a noise monitor in your garage workshop. Provides bonus HUMIDITY and TEMPERATURE readings, and offers 3 ADJUSTABLE SPEEDS (1. Fast 2. Medium 3. Slow) for smooth, readable measurements. 100% new 100% New
