Review: Accurate and Handy performance it's job well. - Before I was having Lutron DB digital meter. 30 to 130 Db. It worked for 20years. Now Display of device is totally black. I ordered this colored Beetech db digital meter. Both devices reading same to same. Secondly now No selector switch of Db range. This device does all by itself. Range 35 Db to 135 Db. Feels good in using all done like Min and Max just select it does all. In Lutron I had captured the fast Display reading. My Home Theatre room SPL 115 Db.
