SAG-A
Stand Alone Gamma Alarm system
This device is adapted for the measurement of Ambient dose equivalent rate, especially for nuclear plant workers. This beacon was conceived to be as resistant as possible. Its cylindrical shape and its bumpers design allow for maximum shock absorptions and drops up to 1.6 m. The beacon polycarbonate body resists repeated hammer blows. The protection factor IP 65 means that the SAG-A is fully protected against dust and splashing water from all directions. The SAG-A beacon is designed to float temporarily.
