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.

Parameters measured:

– User selectable Exchange Rate (3dB, 4dB or 5dB)
– User selectable Criterion Level (75dB, 80dB, 85dB or 90dB)
– User selectable Threshold Level (-5dB, -10dB or OFF)
– Zpeak
– % Dose
– Lep’d (Lex)
– % DOHR (Dose/Hour)
– Pa2h (Lep’d expressed in Pascals)
– Exposure Time
– Lockable Keypad
– Constructed from tough crack resistance plastic
