Testo 816-1 | Sound level meter

Contact Instrument Solutions

The Testo 816-1 class 2 sound level meter is the ideal tool for measurements in the workplaces and industrial environments.

With the touch of a button, the measuring instrument can be switched from Slow (1 second) to Fast (125 ms) response mode. It is also possible to quickly switch between the frequency weighting characteristic curves A and C and vice versa, also at the touch of a button. Characteristic curve A corresponds to the sound pressure sensitivity of the human ear, while characteristic curve C can evaluate low frequency components of a noise.


The integrated data store allows the storage of over 30000 measurement values in the instrument which can be administered using the software included in delivery. In addition to this, the software allows online measurements over a longer period to be carried out.
