820 SLM

Larson Davis Model 820
820 Detailed Overview and Support Pages

Model 820 is an industry standard environmental noise monitor and remains a popular choice for those familiar with the platform. The lack of ability to measure 1/1 or 1/3 octave data, limited memory and serial interface tend to make the 820 a meter most often used by those who have used it in the past, but the low price point makes it an economical logging system.
