Description
PNC-Alpha can store 1000 readings in a non-volatile memory. These readings can be downloaded to PC via USB interface. These readings can also be scanned on LCD display after the counting experiment.
PNC-Alpha, is available in two types ‘Standard’ and ‘Low background’. Both type of units are except BACKGROUND Counts per Hour specification, rest all specifications of both types of units are same. Added advantage of this unit is, it calculates and displays the efficiency.
PNC-Alpha, is ideally suited for Nuclear Counting Experiments carried out in Universities and colleges. It is also useful for radiation counting for Health Physics applications in radioisotope laboratories, nuclear reactors, nuclear power plants, environmental survey labs, 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 mylar face of the detector is just 2 mm above the sample filter paper.
