Castle GA257L Industrial Logging Pocket Dosemeter
The SONUS Pocket Dosemeters are designed to be powerful and easy to use. These dosemeters are small and tough so measurements and data can be collected throughout the working period. Data can be reviewed on screen or downloaded to a PC for further analysis The SONUS GA257L which is also fully compliant with IEC 61252:1993 adds logging capabilities, allowing data to be downloaded to a PC using the Castle dBdataPro noise analysis software, and measures sound pressure levels and Leq
