Description
Dual Channel Alpha Beta Counter Model PNC-αβ, stores 1000 counts (500 Alpha + 500 Beta) data in a non-volatile memory. It generates formatted USB 2.0 output for transferring data to PC. USB male connector on the front panel is provided for transferring the data to PC. Support software for data transfer in Windows environment, is provided with system.
Model PNC-αβ is useful for radiation counting for Health Physics applications in radioisotope laboratories, nuclear reactors, nuclear power plants, nuclear medicine centers etc.
A Drawer Assembly to hold 1″ dia or 2″ dia filter paper is supplied as standard accessory. The detector mounts upside down on the drawer assembly such that myler face of the detector is just 2 mm above the sample filter paper.
40mm thick Lead shield for detector can be supplied at extra cost (as shown in above photograph)
