Sound-level meter, device for measuring the intensity of noise, music, and other sounds. A typical meter consists of a microphone for picking up the sound and converting it into an electrical signal, followed by electronic circuitry for operating on this signal so that the desired characteristics can be measured  Main specification meet IEC 651 type 2. A, C weighting. Max. hold. Fast/slow time weighting. AC/DC output.  AC/DC output. Range: 3 ranges, 30 to 130 dB. Mini pocket size. DC 9V battery ( 006P ) or DC 9V adapter in. Large LCD display, easy to read. Time weighting and frequency weighting meet, Network IEC 61672 type 2. A & C weighting networks are conformity to standards. 0.5" standard out size of the microphone. Time weighting (Fast & Slow) dynamic characteristic modes.
