MPC-900-GF Manual Single Sample Counter

Product introduction

The MPC-900-GFW and MPC-900-GFL are convenient and versatile counter systems with hemispherical gas flow proportional counters for easy portability. These sample counters are ideal for standard health physics applications such as measurements on swabs, air filters, etc. They can also be used in radiochemical applications when only alpha counts are of interest. MPC-900-GFL uses a windowless gas flow proportional counter, which provides extremely high detection efficiency for Alpha rays or low-energy Beta rays. Each counter system is capable of running programs and quality control programs created with DUO Express software, using a direct-connect PIC Link cable to transfer the generated programs directly to the device.
