Radiation Dosimeter Geiger Counter DKG PM1621



PM1621 - Unique electronic dosimeter for measurement of the exposure levels from X-ray and gamma radiation sources and recording even the minor fluctuations of the natural radiation background. These dosimeters monitor and measure the personal dose equivalent Hp(10) and personal dose equivalent rate Hp(10) from both gamma and X-ray radiation. Their ability to compensate for the energy variations in the range from 10 keV upto 20MeV allows these personal dosimeters to make extremely accurate measurements.


- Monitoring and measuring the gamma and X-ray dose and dose rate across a wide energy range up to 1 Sv/h (100 R/h)
- Alerting the user via an audible alarm when the preset dose and/or dose rate thresholds are exceeded
- Recording and storing data for up to 1000 events in their non-volatile memory
- Transmitting all recorded data via an infrared channel to a PC for further processing and analysis
