AT2503B budget digital dosimeters are built on the success of their predecessors AT2503 and AT2503A. New devices have improved electronic components and design. AT2503B dosimeters enjoy a larger screen, a broader range of dose equivalent rates from 0.1 μSv/h to 10 Sv/h, and a wider energy range from 50 keV to 10 MeV. The dosimeters have exceptionally reliable Geiger-Muller tube as a radiation sensitive detector core and are designed for measurement of personal dose equivalent and personal dose equivalent rate of continuous X-ray and gamma radiation.
Main features:
- High measurement accuracy with intrinsic background compensation
 - Small dimensions and weight
 - Resistance to impacts and vibration
 - Wide operation temperature range
 - USB readout and software to create an easy to operate staff radiation exposure control database
