Model # 322A

PCE-322A is a handheld, portable, professional Class II sound level meter or decibel (dB) meter with built-in data-logging or data-recording functionality.
It is ideal for real-time noise measurement as well as for long-term noise exposure monitoring over time. A mini tripod is included in the delivery contents, as is a wind noise suppressor.
The recorded decibel readings help users determine if and what protective measures need to be taken to ensure overall health, safety and productivity in industrial, commercial, occupational, educational and residential environments. The decibel meter can also be used to evaluate acoustics for audio installations.
