MPC-9604 α/β multi-detector counting system

The MPC-9604 is designed with performance features designed to simplify setup, operation and maintenance.

•ofThe connection is AC power,USBcomputer control andP-10gas supplyYes, it consists ofGas pro™Monitor and stop counting when a gas failure is detected.

•straightGuan’s control software provides simple data access and reporting capabilities, allowing for limiteddrastically reducetraining and setup time. Each detector has its own sample drawer for independent sample loading and control, true“counting toMDA”, andwith“ MDAcount”toOptimize throughput.

•Maintenance does not require rear access to the detector and electronics modules, which can be accessed from the front panel. The detector window can easily be10pointscan be replaced within the clock without interrupting the operation of other detectors。

Factory measurement conditions

• Determination of 4π efficiency using NIST traceable area source @ 1/8"
• Measure background at natural background 8 µR/hr

Customer must provideAC power, P-10 gas supply, calibration source, and a suitable surface on which to place each MPC-9604. The supporting surface must be able to safely support the 1,200-pound weight of each MPC-9604.
