Low Noise Sound Level Meter.
Low Decibel Noise Level Measurements.
SoundAdvisor 831C-LOWN Low Noise Meter, Microphone and Preamplifier.
The SoundAdvisor™ Sound Level Meter 831C paired with the Low Noise Microphone and Preamplifier 378A04. Easily measure very quiet sounds. You can measure less than 6.5 dBA with an easy handheld, portable system.
Due to the innovative design of the 378A04, which uses a prepolarized microphone and ICP® (constant current) interface, the combination produces a highly portable system that is battery-powered and intuitive to use.
The Model 831C-LOWN configuration is ideal for measurements where noise levels are extremely low, such as very quiet soundscapes and quiet machines.
Because the 831C-LOWN consists of the popular SoundAdvisor Model 831C paired with the 378A04 low-noise microphone, it can be used with the wide range of 831C accessories. For example, use with the DVX012 Ethernet dongle to provide network connectivity or the SoundAdvisor Portable Noise Monitoring System Model NMS044 to create a low-noise portable monitoring solution.
