Review on 🔊 Professional 30DB-130DB Backlight Measuring Instrument: Accurate Sound Level Monitor by Raffy Baer

everything works great! It works just like a professional phonometer. The meter can measure sound levels from 30 to 130 decibels, which meets my needs. When I use it at night, the backlight helps a lot. The PC program is easy to use. What I need to do is connect the blood glucose meter and my computer with a USB cable. The software sets up automatically and I can save the recording to my computer for further processing. I RECOMMEND to users who are looking for a comfortable and quality sound level meter at a reasonable price.
