Personal Gamma Radiation Dosimeter EcotestCARD DKG-21
Downloads:
PDF Instruction 1
The EcotestCARD DKG-21 is a compact and highly reliable personal dosimeter designed for continuous monitoring of individual dose equivalent (DE) and dose equivalent rate (DER) of gamma and X-ray radiation. Built around an energy-compensated Geiger-Muller counter, it delivers exceptional measurement accuracy across a broad energy range from 0.05 MeV to 6 MeV. Its proven field performance was demonstrated during emergency operations at the Fukushima NPP, proving its durability under harsh environments.
Equipped with an integrated non-volatile memory, the device records dose accumulation history linked to a real-time clock. Data can be seamlessly transferred to a PC via an infrared interface (IrDA) for automated processing, generating analytical reports, and long-term archiving. The instrument supports independent threshold programming for both dose rate and accumulated dose, triggering visual and audible alarms upon limit breaches.
With an ultralight credit-card form factor weighing only 80 grams, an IP31 enclosure, and up to 3,000 hours of continuous operation from a rechargeable Li-ion battery, the EcotestCARD is the premier choice for professional B2B individual dosimetry systems.
