ZXONIC ZX3300 Sound Level Analyzer

The ZX3300 Sound Level Analyzer is a next-generation noise measurement instrument that employs digital signal processing (DSP) and network technology. It is capable of simultaneously measuring multiple evaluation parameters. Its modular design allows users to select appropriate modules based on their specific needs. The instrument features large-capacity data storage, audio recording, USB flash drive support, and a card reader. It also integrates wireless data transmission modules such as 4G, Wi-Fi, and Bluetooth, along with a positioning system, enabling noise measurement and geolocation data acquisition. An optional external micro-printer can be used for on-site printing of measurement results. This instrument is widely applicable in environmental protection, occupational hygiene, industrial enterprises, and research and education, supporting various noise measurement tasks, including environmental noise assessment, occupational noise exposure evaluation, and machinery noise analysis.
