The Testo 816 (0563 8165) Sound Level Meter is the ideal sound level measuring instrument for assessors, workplace measurements and for the measurement of industrial and environmental noise.

Using the Fast/Slow button, the measurement time can be set from 1 s to 125 ms, in order to better evaluate the noise source. The frequency analysis can also be switched from characteristic curve A to C. The characteristic curve A corresponds to the sound pressure perception of the human ear, whereas characteristic curve C can also evaluate the low-frequency components of a sound.

The testo 816 also has an AC and DC output. Via the AC output, recorders or amplifiers can be connected directly to the instrument, and via the DC output, graphical recorders or data loggers can be used easily and directly on site. The analog bar graph display offers the user a fast overview over the complete measuring range.

With the help of the optional calibrator (available separately), the measuring instrument can be recalibrated directly on site with the screwdriver provided. The wind protection cap included in delivery ensures correct measurement results when measuring outdoors, and if required can protect the microphone from dirt and dust.
