It measures from 30 dB to 130 dB (A) and records Leq, SEL, maximum, minimum, and C-weighted peak levels. This makes it suitable for assessing noise at workplaces, evaluating environmental noise, and testing product noise in Sri Lanka.\n\u003c\/p\u003e\n\n\u003cp\u003eDiscover our complete selection of \u003ca href=\"\/collections\/sound-level-meters\" target=\"_blank\"\u003eSound Level Meters – specifications, features, and noise testers in Sri Lanka!\u003c\/a\u003e\u003c\/p\u003e\n\n\u003cp\u003e\n  A ½-inch pre-polarized condenser microphone, A\/C\/Z frequency weighting, and Fast, Slow, Impulse, and Peak time weighting give you full control over your measurements. For long surveys, you can set integration times from 10 seconds up to 24 hours, store readings on a micro SD card, and transfer data to a PC through USB. The meter also provides analog and RS-232 (TTL) output.\n\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdl class=\"package-list\"\u003e\n
