UT353BT can transfer measurement data through bluetooth to UNI-T’s custom mobile APP (iENV) for further analysis, storage, and export. iENV can be downloaded from Google Play, Apple Store or UNI-T’s website by searching ‘iENV’.A sound level meter is used for acoustic (sound that travels through the air) measurements. It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability.Sound level meters look quite simple. They have a pointy stick at the top, which is the microphone that samples and measures the sound. The stick keeps the microphone away from the body of the instrument, cutting out reflections, and giving a more accurate measurement. Inside the square box at the bottom of the meter, electronic circuits measure the sound detected by the microphone and amplify and filter it in various ways before showing a readout on a digital LCD display.
