Digital Sound Level Meter 30-130dBA, 0.1 dB Resolution ±1.5dB — Decibel/Noise Tester with AC/DC Output, Max Hold, A & C Weighting, Auto Power-Off

Accurate, wide-range noise measurement for machines, music, neighbors, speech therapy and more. This sound level meter offers high precision (+/-1.5dB) with 0.1 dB resolution and covers a broad measuring band of 30dBA-130dBA, making it suitable for both professional checks and everyday noise monitoring. Smart power and status features help avoid interruptions: the meter has an automatic power-off to conserve battery, a low-power indicator to prompt timely battery replacement, and a self-check routine that runs for 10 seconds at each power-up. For measurement control and protection, the instrument provides a Max Hold function to freeze the highest reading and an over-range warning to help you pick the proper range. Available ranges to choose from are (30-80dB; 50-100dB; 60-110dB; 80-130dB) so you can match the scale to the environment. Connectivity and analysis: built-in AC/DC output ports on the side let you hook the meter to external gear such as an X–Y recorder or a frequency analyzer for detailed statistical review. Designed to meet different testing needs, the meter supports Frequency Weighting C for mechanical noise and Weighting A for sounds as perceived by the human ear. Two time weightings are available — "Fast" for instant readings and "Slow" for averaged measurements — giving you flexibility in how results are captured.
