Compact Digital Sound Level MeterIf you're into audio, you can't not have a sound level meter (SPL meter) and now you don't have to have a six figure salary to afford one. Featuring a wide dynamic range from 30 to 130dB, it can measure both A and C weightings to get the right response for the human ear and can have fast or slow responses to get an ambient reading or a short noise. Includes data hold and min max functions, as well as tripod mount for prolonged use. Great for car audio
