This sound level meter is built for fixed-location noise monitoring, measuring 30-130 dB at +/-1.4 dB accuracy on a 7-inch color TFT touchscreen. It logs continuously to 16GB of onboard memory at user-set sampling intervals from 1 second to 24 hours, exporting time-stamped CSV data, and offers switchable A/C frequency weighting plus Fast/Slow response speeds. A built-in desk stand and wall-mount bracket let it serve as a permanent installation for workplace or facility noise compliance checks.
