GRAETZ GAMMATEST 1 Doserate Alarm Unit

GRAETZ GAMMATEST 1 Doserate Alarm Unit

The GAMMATEST 1 is a light, battery-operated doserate alarm unit for the personal radiation protection, detecting gamma and X-rays. The device disposes of four alarm thresholds triggering an acoustic alarm when being exceeded.

The housing is made of high impact plastic with metallized surface, thus achieving a shielding against electromagnetic influence. It can be easily decontaminated and it is splash-proof.

The GAMMATEST 1 is approved for the use at fire brigades (German Fire Brigades Approval No.: DLW/FW/GSF 127702/2).

Measuring size: ambient doserate equivalent H*(10).

It is preferably used to determine the restricted areas where a doserate of 25 µSv/h is achieved.
