Handheld Digital Sound Level Meter 30~130db — 9.6" LCD Backlight Portable Noise Meter

Portable digital sound level meter with a measurement range of 30~130db and a large 9.6" LCD display with backlight for easy viewing in dim environments. The unit includes an alarm feature: if the measured level exceeds the preset alarm threshold the meter emits a beep, locks the current reading and flashes for 2 minutes. Automatic data logging stores readings every 2 seconds, with each saved value representing the highest noise level recorded during that 2-second interval; stored data can be retained for up to one year. A USB cable lets you connect the instrument to a computer to download records, capture 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.
