MPC-900-DP manual single sample counter

The MPC-900-DP is a convenient, versatile "desktop" counter that uses dual scintillator detectors, requires no working gas, and is easy to carry. Optional anti-coincidence guard detectors reduce background levels. DUO Express software allows users to perform data management and quality analysis through easy programming. Multiple devices can be connected for user convenience. This type of counter is ideal for standard health physics applications such as wipe sample measurement, or air filter paper measurement.
