PM1401K-3 is the smallest and the most lightweight instrument in the world, which is capable to operate simultaneously as an alarming device, search instrument, survey meter, spectrometer and identifier.
The instrument can be used both indoors and outdoors and is intended for everyday and/or emergency use by officers of radiological and isotope laboratories, specialists of different industries, agriculture, transport, medicine, customs and border services, firefighters, military, police and other first responding agencies.

Operation Principle
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.
Modifications:
- PM1401K-3E – gamma-neutron modification without functions of 137Cs activity measurement and radionuclides indentification.
- РМ1401K-3P – modification is equipped with built-in alpha, beta, gamma and neutron (based on three scintillation units) detectors;
- РМ1401K-3М – modification is equipped with built-in alpha, beta and gamma detectors, without neutron detection capabilities.
- РМ1401К-3PM – modification is equipped with built-in gamma and neutron (based on three scintillation units) detectors, Bluetooth module, with dose equivalent measurement capabilities;
