Alat Uji Kebisingan Suara / CENTER 322

Alat Uji Kebisingan SL322

Description:
Datalogs 32000 readings of ambient sound levels in dBA dBC 30-130dB

The Center 322 is an easy to use and accurate hand held sound level meter with Data Logging. It records in dBA and dBC scales and the data can be downloaded to a PC for analysis. While not an integrating Dosimeter, the Center 322 can give a good indication of exposure to sound over an extended period. The bar graph indicator gives operator feedback on the trends of the readings.
The Center 322 comes complete and ready to use in a carry case with software, and interface cable.
