� have background radiation detecting ability
� may cumulative dose and dose rate measure and display the same time
� may automatic change the unit
� may automatic save the cumulative dosage and the cumulative from date
� may preplace dose rate and cumulative dose alarm threshold
� voice,vibration and mute type of alarm or alarm types assemble
� low power consumption design and real timev oltage display
� the cumulative dose can be saved a long time after
� have real time time clock feature and the the colock run oridinary fater outage
� internally installed failure testing and dose rate overload alarm and self protect ability


This instrument have a measuring range 5 times larger than other ordinary models,its response
time is 2 times quicker than ordinaries,and its smaller,sensitiver,lighter,easy to carry.
