Portable sample counter with a windowless scintillator, providing simultaneous alpha and beta measurements of samples, filters and test sources.
The RadEye HEC+ is a portable sample counter providing simultaneous alpha and beta measurements. Samples are placed in a sample drawer with adapters for a variety of circular and rectangular air filters and test sources, and detector performance is easily verified with a Lutetium Test Adapter.
Source tests are automatically prompted at user-defined intervals, and all check source events are logged. A carrying handle and rechargeable battery make the unit easy to use in the field, and readings are logged automatically for retrieval to a PC.
