The Larson Davis Model 831 Class 1 Sound Level Meter is a versatile instrument, which performs the functions of several instruments. It puts the combined features of a precision Class 1 sound level meter, environmental noise logger, personal noise dosimeter, and a real-time frequency analyzer in the palm of your hand. The Larson Davis Model 831 is a fifth generation Larson Davis sound level meter, designed for simple single handed operation, yet is fully featured, smart and versatile with an extensive swuite of firmware options. The design of the Model 831 was based on countless inputs from our customers. It expands upon the Larson Davis tradition of delivering value, innovation and function in a rugged single-handed expandable package and is backed by a 2-year Factory Warranty, 24-hour application support and accredited factory service/calibration.
