GWL 10m


Gamma warning lamp with adjustable alarm thresholds for room monitoring and for the determination of restricted areas.

 

Fields of application

NDT, Fire Brigades, Civil Defence, Nuclear Technology, Industry

 

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
