    The MPC-900-GFW and MPC-900-GFL are convenient and versatile benchtop counters equipped with hemispherical gas-flow proportional type detectors that support easy portability. These sample counters are ideal for standard health physics applications such as smears and air filters. They can also be used for radiochemistry applications when alpha only counting is of interest. The MPC-900-GFL uses a windowless gas-flow proportional detector that delivers higher efficiencies for projects involving alpha emitters and higher activity low-energy beta emitters. Each counter has the ability to program routines and QC charts on a PC running the included DUO Express software, then transfer the routines to the instrument using a direct-connect PIC Link cable.
