✅ KEEP IT DOWN!!!: The AirKnight digital dB meter is just what the doctor ordered! Now, you'll have exactly the authority (and numeric proof) you need to tell your kids, colleagues, classroom, band, or that noisy neighbor to "take it down a notch."
✅ EXTRA LARGE LCD DISPLAY & WALL MOUNT: 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.
✅ VERSATILE & LONG-LASTING: Our classroom noise meter can be used all over your space. It's wall mountable with a 10ft power 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.
✅ BONUS FEATURES: 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 AirKnight sound level tester has 3 ADJUSTABLE SPEEDS (1. Fast 2. Medium 3. Slow) to make reading it a breeze.
✅ 2 YEAR WARRANTY AVAILABLE: AirKnight is an American company that works tirelessly to ensure the overall quality of each portable decibel meter with rigorous testing. Simply put: if you are not happy, our US-based team will replace your unit or give you your money back – no questions asked!
