Background subtraction
Enhances the detectability of very low activities.

DPM calculation
With the entry of individual values of efficiency can be performed automatically.

High count rates
For high count rates up to 200,000 cps the system is equipped with a dead time correction.

Print out
All parameters as well as results can be obtained via RS 232C port.
