Frequency evaluation according to characteristic curves

A and C

Easy to adjust

Maximum and minimum store

Switchable time evaluation Fast/Slow

The testo 815 is the ideal instrument for the evaluation of

sound level in everyday work. The instrument can be used

for monitoring measurements in the areas of air conditioning

or heating, on combustion plants or at workplaces, however

machine or discotheque noise can also be evaluated quickly

and precisely.

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

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

source. The frequency analysis can also be switched from

characterisitc curve A to C. The characteristic curve A

dB

corresponds to the sound pressure perception of the human

ear, whereas characteristic curve C can also evaluate the

low-frequency components of a sound.

With the help of the optional calibrator, 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.
