Dose Rate Alarm Unit
GRAETZ GammaSmart V.Ex

for personal radiation protection in explosion endangered atmospheres

The dose rate alarm unit "GammaSmart V.Ex" is a very robust and easy to handle pocket-sized alarm unit. It is accumulator operated and designed for personal radiation protection.

It detects gamma radiation and X-rays, indicating these with clear optical and acoustical single pulses. An increasing dose rate leads to an increasing pulse rate.

The splash-proof aluminium housing (IP 54) ensures a shielding against electromagnetic influence. An optical battery control indicates the GammaSmart's readiness for use.

Recharge of the built-in accumulator requires the recharger unit "GRAETZ 462L" (necessary accessories).
