It supports A\/C frequency weighting, FAST\/SLOW modes, and a data logging function that generates graphs. Additionally, it allows you to monitor ambient temperature and humidity. All of this makes the device ideal for professional acoustic measurements, monitoring working conditions, and more.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cbr\u003e\u003cimg alt=\"Portable decibel meter with a foam-covered microphone, displaying a reading of 77.3 dB on a dark, textured background\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/21652\/28608\/2.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch3\u003ePrecise noise measurement\u003c\/h3\u003e\u003cbr\u003e\u003cp\u003eThe device uses a condenser microphone, which ensures high sensitivity and measurement stability. The FDM-02 model provides accurate real-time sound level readings, allowing for effective monitoring of noise levels in rooms, workplaces, or public spaces. The easy-to-read display presents current measurement values clearly, facilitating quick analysis of results. Additionally, the meter supports two frequency weighting modes—A and C—allowing you to adjust the measurement method to the type of noise being analyzed. You can also use the FAST and SLOW modes, which enable faster or more stable measurement sampling depending on operating conditions.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cbr\u003e\u003cimg alt=\"Sound level meter with a built-in screen on a bright, blurred interior background\" border=\"0\" src=\"https:\/\/assets.innpro.pl\/21652\/28608\/3.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch3\u003eTemperature and Humidity Measurement\u003c\/h3\u003e\u003cbr\u003e\u003cp\u003eThe device not only allows you to check sound levels but also to monitor ambient temperature and humidity.
