DoseGUARD™

  




Application / Description
DoseGUARD™ personal alarm dosimeters are precision instruments for ensuring that radiation doses are kept as low as reasonably achievable.
The dose rate or cumulative dose is shown on an LCD display. An audible alarm sounds if a preset dose or dose rate is exceeded. The instrument can also be set to give an audible warning of the instantaneous dose rate.
Energy compensation circuits ensure high accuracy. Key parameters are stored in EEPROM and are retained even if the battery is removed.
The dosimeter casing is robust and splash-proof, and is constructed from smooth high impact plastic for easy decontamination. The instrument has been designed to protect the readings against accidental erasure due to mechanical shock or an RF field. It is battery operated, and requires one standard AAA size alkaline cell.

New features:
- Enhanced RF immunity
- Ruggedised clip fixing
- Easier to decontaminate
- Louder volume
