Overview

The MPC-900-DP is a convenient and versatile benchtop counter equipped with a dual phosphor scintillator type detector that supports gasless operation and easy portability. This sample counter is ideal for standard health physics applications such as smears and air filters. The MPC-900-DP 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.

Part Number: 105-900-DP
