Digital Sound Level Meter 30~130db — 9.6" Large LCD Hanging/Desktop Decibel Monitor

Features a super-large 9.6" backlit LCD for clear, easy-to-read measurements even in dark environments. Alarm function: when the measured level exceeds the set alarm value the unit emits a beep, flashes and locks the displayed reading for 2 minutes. Automatic data logging saves readings every 2 seconds; each stored entry represents the maximum noise value during that 2s interval, with storage capacity lasting up to one year. USB connectivity allows connection to a computer via USB cable to download records, collect samples and print charts and dates. Wall-hanging design includes a hanging hole for mounting, and the meter can also stand freely on a table. Precision measurement.
