MPC-900-GFW-2/GFL-2
Manual single-sample alpha/beta counter with gas-flow detector
Benchtop gross alpha/beta counters with a hemispherical gas-flow proportional detector, for health physics such as smears and air filters and for radiochemistry when only alpha counting is of interest. The windowless GFL-2 gives higher efficiencies for alpha emitters and higher-activity low-energy beta emitters. Routines and QC charts are programmed in DUO Express and transferred via PIC Link.
