PM1401K-3P - Multipurpose Hand-Held Radiation Monitor/Identifier

Instrument performs continuous measurement of ambient dose equivalent rate of gamma and X-ray radiation in the wide energy range, monitors alpha, beta and neutron radiation, operates as spectrometer of gamma radiation and radioisotope identifier , and measures food/soil contamination with ¹³⁷Cs radionuclide.

Instrument is equipped with built-in audible and visual alarms, GPS module, USB interface for PC communication. Non-volatile memory allows recording and storing up to 10 000 events. PM1401K-3 has compact size and lightweight, bright and color LCD, shockproof hermetic case and can be used in both indoor and outdoor environments.
