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
The instrument performs continuous measurement of ambient dose equivalent rate and dose equivalent of gamma and X-ray radiation in the wide energy range, monitors neutron radiation, operates as spectrometer of gamma radiation and radioisotope identifier.
The instrument is equipped with built-in audible and visual alarms, Bluetooth and GPS modules, USB interface for PC communication. Non-volatile memory allows recording and storing up to 10 000 events and 1 000 gamma spectra. PM1401K-3PM has compact size and light weight, bright and color LCD, shockproof hermetic case and can be used in both indoor and outdoor environments.
Modifications:
- РМ1401K-3М – modification is equipped with built-in alpha, beta and gamma detectors, without neutron detection capabilities;
- РМ1401K-3P – modification is equipped with built-in alpha, beta, gamma and neutron (based on three scintillation units) detectors;
- РМ1401К-3PM – modification is equipped with built-in gamma and neutron (based on three scintillation units) detectors, Bluetooth module, with dose equivalent measurement capabilities;
- PM1401K-3E – gamma-neutron modification without functions of 137Cs activity measurement and radionuclides identification.
