Product parameters:

Customized processing: no
Brand: meet macros
Model: AWA6223S
Type: low-frequency sound level meter

Is a kind of multi-frequency (F) or more sound pressure level (s) of sound calibrators, used to measure sound pressure sensitivity of the microphone, checking or adjusting the total sensitivity of the acoustic measurement device. Instrument internal temperature, humidity sensors, can measure ambient temperature, relative humidity, also optional wind speed measurement function, the internal test records can be saved.

Features: Executive GB/T 15173-2010/IEC 60,942:2003 standards;

S-types in the sound pressure level the sound calibrator has 4 sound pressure levels, can detect the level of acoustic measurement device of linear;

F-type multifrequency sound calibrator has 4 frequency, suitable for frequency calibration;

AWA6223 built-in pressure sensors capable of measuring atmospheric pressure, and can automatically correct the air pressure and the accuracy is 1.
