Multipurpose Hand-Held Radiation Monitor/Identifier - РМ1401К-3/M

PM1401K-3 Multipurpose Hand-Held Radiation Monitor/Identifier belongs to the new family of Polimaster extremely sensitive and compact multipurpose hand-held radiation monitors.

PM1401K-3 can continuously measure ambient dose equivalent rate Ḣ*(10) of gamma and x-ray radiation in the wide energy range, monitor alpha, beta and neutron radiations, work as spectrometer of gamma radiation and radioisotope identifier, and measure food/soil contamination by 137Cs radionuclide.

All operation history is stored in the instrument’s non-volatile memory and may be downloaded to a personal computer through a USB interface. PM1401K-3 is also equipped with built-in GPS to enable geocached data logging.

The instrument can be used in both indoor and outdoor environments and is intended for everyday and/or emergency use by firefighters, military, police and other first responding agencies.
