Feature●Wide Range Measure: The noise meter measures a wide range of 30 - 130 dBA, 35 - 130 dBC, and has a high precision of ±1.5 dB (at 94 dB and 1 kHz), so you can measure a wide range of sounds from whisper to construction sounds●"Close to the size of the actual sound" The value measured by the A feature is suitable for use when you want to measure sounds that you actually feel and general daily noise. C characteristic is measured by the sound pressure, making it ideal for sound impacts and loud noise in continuous areas●"More closer to the ear" time weighting features are available in two types: F (Fast) and S (Slow). F records large numbers when sound occurs, and gradually attenuates the numerical fluctuations close to the human ear. In contrary, the S is recommended for loud sounds that can be used to prevent neighbors problems caused by noise●Easy to operate: Just turn the power and press the start button to measure your numerical values. This is an easy-to-read capital digital LCD with a MAX hold function. Analog voltage output terminal (AC/DC)●Windproof, Standing Type: Equipped with a condenser microphone, the microphone part is equipped with a sponge, so you can measure accurate data even when it is blown in the wind. Comes with a tripod hole so you can attach it to your camera tripodDescription
