Measuring noise at work doesn’t need to be a time-consuming task. The Optimus+ Red noise at work sound level meter makes noise level measurements incredibly easy and straightfoward, as it uses advanced digital acoustic technology to save you time while capturing all essential noise level data simultaneously. The instrument captures sound pressure level (SPL), time weighted and frequency weighted values, and octave band data at the press of a single button. You’ll never need to worry about missing something or choosing the wrong function: just turn it on, calibrate it, and get measuring!
