Digital Personal Dosimeter PDM-222

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.
