The testo 815 is the ideal instrument for the evaluation of

nnnn

sound level in everyday work. The instrument can be used

nnnn

for monitoring measurements in the areas of air conditioning

nnnn

or heating, on combustion plants or at workplaces, however

nnnn

machine or discotheque noise can also be evaluated quickly

nnnn

and precisely.

nnnn

Using the Fast/slow button, the measurement time can be

nnnn

set from 1s to 125 ms, in order to better evalaute the noise

nnnn

source. The frequency analysis can also be switched from

nnnn

characterisitc curve A to C. The characteristic curve A

nnnn

corresponds to the sound pressure perception of the human

nnnn

ear, whereas characteristic curve C can also evaluate the

nnnn

low-frequency components of a sound.

nnnn

With the help of the optional calibrator, the measuring

nnnn

instrument can be recalibrated directly on site with the

nnnn

screwdriver provided. The wind protection cap included in

nnnn

delivery ensures correct measurement results when

nnnn

measuring outdoors, and if required can protect the

nnnn

microphone from dirt and dust.
