Dose rate meter GRAETZ X5C FW
The dose rate measurement system GRAETZ X5C FW was modified in cooperation with the Hamburg Fire Department and has an official approval for the fire department. The GRAETZ X5C FW has a dose display as well as a warning function for personal radiation protection when handling ionizing radiation. The measuring system is also equipped with an RS-232 interface and an interface for connecting external probes.
