Features
The GWL10m is an accumulator operated, self-contained dose rate alarm unit for the detection of gamma radiation and X-rays with four alarm thresholds, triggering optical and acoustic alarm when being exceeded. The acoustic alarm can be switched off, if required.
The instrument, designed for operations in "heavy-duty" environments,
is EMC-proof and equipped with a robust and splashproof housing.
The GWL10m is preferably used for room monitoring and for the determination of restricted areas where a given dose rate has been achieved.
The GWL10m is supplied together with a recharger unit for recharging the built-in accumulator.
Optional accessories
- robust tripod
- special version with motion sensor triggering an acoustic alarm when a person approaches towards a danger zone with increased radiation level
