Electronic personal dosemeter GRAETZ GPD150G

The GRAETZ GDP150G is a compact, robust and battery operated electronic personal dosemeter. The so-called alarm dosemeter is equipped with a dose and dose rate warning function at a measurand of Hp(10). The GRAETZ GDP150G is particularly convincing in the case of fire brigades and other forces of civil defense due to its high reliability and ease of use. Operational forces are offered the possibility of permanent self-monitoring.
