The POLIMASTER PM1401K-3M is a multipurpose handheld radiation monitor and identifier for customs, HAZMAT, emergency services, and first responders.
The PM1401K-3M is a multipurpose hand-held radiation monitor and radionuclide identifier designed for quick and reliable measurement of gamma dose rate, detection of alpha, beta, and gamma sources, measurement of radiation flux density, gamma spectra acquisition, radionuclide identification, and food/soil contamination measurement with 137Cs. This gamma-only model (without neutron detector) features a shock and water-resistant IP65 case, storage of up to 10,000 events and 1,000 spectra, audible/visual/vibration alarms, adjustable radionuclide libraries, USB PC communication, and built-in GPS. Ideal for customs, HAZMAT, emergency services, industrial facilities, and first responders.
