3-In-1 Decibel Meter Sound Level Reader+Humidity & Temperatu

Our digital sound level meter is equipped with a high-definition backlit LCD screen, so that you can effortlessly read it throughout the day at your convenience. Unlike handheld sound level meters, our premium wall-mountable dB meter is simple to set up and perfect for continuous monitoring.
Our classroom noise meter can be used all over your space. It's wall mountable with a 10ft cord, flat-bottomed for placing on tables, and lasts for hours unplugged with a 2000MaH battery. Also, it can be a home theater SPL meter by the TV or in your garage workshop.
We've included bonus HUMIDITY and TEMPERATURE readings in addition to bringing you the best decibel meter we could. And to top it off, the sound level tester has 3 ADJUSTABLE SPEEDS (1. Fast 2. Medium 3. Slow) to make reading it a breeze. color:As shown
