The 831C SoundAdvisor is designed to make noise measurement easy. With its color display, connectivity, extensive software features, and small form factor, the SoundAdvisor is an ideal choice for handheld operation. Un-attended measurements are simplified, with the ability to control and monitor data via any internet connected computer or mobile device. The 831C can be controlled remotely as if the operator were directly in front of the meter.  It is extremely versatile, performing the functions of several instruments. It puts the combined features of a precision Class 1 sound level meter, environmental noise analyzer, and a real-time frequency analyzer in the palm of your hand or on a network. Like all Larson Davis products, it comes with a 2-year factory warranty.
