Function and Applications

This hand-held device measures radioactive radiation (alpha-, beta-, gamma-) permanently. Every single type of radiation can be selected by a switch. The measurement datas are stored directly in the internal memory.

Benefits

The measurement datas can be analysed with the help of the freely downloadable Windows and MacOS Software.
