testo 815 / 816

Measuring Sound Level from 30...130 dB Sound level measurement – To DIN/IEC 60651, Class 2



Real-world Sound Level Measuring Instruments Whether at a working place , in machine halls, offices, in discotheques or in the environmental field, it is important to control sound levels, which is often prescribed. testo 815 and 816 are easy to operate, precise sound level measuring instruments of the accuracy class 2. A calibrator for controlling and calibrating can be ordered as an accessory.

The Parameter Sound Next to the human eye the human ear is the sense organ used the most. Due to sound occurences in our ambience - be it a tone, music, bird twittering or machine noise - we participate in our ambience via the ears. The ears are a precious sense organ, which is necessary to be protected. Especially in the job-related everyday life, sound is generated by machine noise in a way we sense as disturbing. Everybody knows, noise and sound occurences, which are too loud on a continuing basis can damage the ear permanently. The new sound level measuring instruments testo 815 / 816 are modern sound level measuring instruments, which allow us to measure and evaluate sound, noise or pure tones.

testo 816 The instrument for evaluators, workplace measurements and measuring industrial and environmental noise. The bigger model offers additional features compared to the testo 815, which predestine it especially for evaluators, workplace measurements and measuring industrial and environmental noise.

Additional benefits of testo 816: • Automatic range switchover

• The “A” weighted graph corresponds to the hearing sensation of the human ear. • The “C” weighted graph is used for measuring low frequency sounds.

easy calibration with a screwdriver

Sound Level Calibrator Sound level measuring instruments should be re-calibrated in case of changes in place or temperature. With the help of the calibrator, available as an accessory, both instruments can easily be controlled and adjusted. Two levels can be adjusted (94 and 114 dB). It is as well suited for 1/2 inch and 1 inch microphones of other makes.

conditions, the measuring instrument should be adjusted with a calibrator. 2 levels can be adjusted at the calibrator (94 dB / 114 dB).

Removable adapter ring for calibrating instruments with 1 inch microphones. With inserted adapter ring 1/2 inch microphones can be fitted (testo 815 / 816).
