The IPC-650-HP  ultra-low background windowless automatic is a newly redesigned instrument based upon the IPC-650, which was the foundation product of Protean.  The ICP-650-HP incorporates a built-in color touch screen Interface and is targeted toward health physics applications. This hemispherical, windowless, gas-flow proportional counter design offers the best efficiencies available for low-energy beta and alpha particles.
