Description:
This system comprises of one industrial noise dosemeters for measuring Dose %, Projected Dose, Daily Exposure (Lepd) and True Peak in a single package. Ideal for large numbers of staff, making it easier and more cost-effective to initiate a wide ranging dosimetry programme. The GA257L logging dosemeter offers a full day's exposure data which can be downloaded to the dBdataPro noise software for further evaluation and storage.
Includes:
- 1x GA257L Personal Sound Exposure Meters
- GA601 Single Level Calibrator
- PC007 dBdataPro Noise Analysis Software and Cable
- KA007 5 Meter Kit Case
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.
