Digital Personal Dosimeter For Radiation Detection.

Brand: HITACHI JAPAN

Electronic Personal Dosimeter

Model: PDM-222

PDM-222 can use to be put in the coat pocket to measure the X and Gamma ray with high sensitivity. It has a LCD to display the measurement，and can be operated with the buttons on the dosimeter. Caution:no sensitive for X-ray which's tube voltage under 100kVp.

Advantage

■ Small，Light weight，Designed wearing in the coat pocket. ■ Audio alarm. ■ 1μSv〜10Sv dose range. ■Dose rate measurement available. ■ Data hold on function.
