TESTO 816-1 Portable Sound Level Meter

The testo 816-1 is ideal for sound level measurements at workplaces, in industrial and production halls, and in public places.

With the touch of a button, the measuring instru-ment can be switched from Slow (1 sec.) to Fast (125 ms). It is also possible to 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 characte-ristic curve C can evaluate low-frequency components of a noise.

Integrated Data Storage:
The integrated data store allows the storage of over 30000 measurement values in the instrument, these 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. With the optional sound calibrator and the adjustment ac-cessory included with it, the testo 816-1 can be recalibrated on site.
