PM2012MA is a two-in-one instrument, which combines functions of chemical detector and gamma radiation detector in one unit. Instrument measures ambient dose equivalent rate and ambient dose equivalent of gamma- and X-ray radiation. PM2012MA also detects vapors emitted from chemical warfare agents (CWA): organophosphorus compounds (sarin, soman, V-gases) and arsenic-containing compound (lewisite). If the preset thresholds of the radiation levels are exceeded, the instrument alerts by audible and visual alarms. PM2012MA has extended measurement range of the dose equivalent and the lower main relative error of the dose equivalent rate measurement.
PM2012M/MA/MB can be used by first responders, police officers, customs and border patrol services, HazMat Teams.
Operation Principle
PM2012M/MA/MB consist of two independent modules:
- Gamma-radiation detector module
Registration of the gamma radiation is carried out on the basis of Geiger-Muller counter, enabling continuous monitoring of the ambient dose equivalent rate and dose equivalent of gamma radiation and alarming when the preset threshold levels are exceeded.
- Toxic chemical vapors detection module
Detection of the toxic vapors in the air is carried out with the help of ionization chamber, equipped with beta-radiation source Ni-63. The ambient air is pumped through an ionizing chamber by a micropump, and CWA vapors in the air are monitored. To separate organophosphorus compounds and arsenic-containing compounds the polarity of voltage signals is determined.
Modifications Available
PM2012M – base modification
PM2012MA – differs within the limits of the dose accuracy and extended measurement range of the dose equivalent
PM2012MB - differs within the limits of the dose accuracy and extended measurement range of the dose equivalent, equipped with the Bluetooth and USB modules (for data exchange with smartphone and PC). *The instrument is subjected to certification.

Data Processing Software
Software enables the operator:
- to change operational parameters of the connected instrument
- to retrieve data from the instrument non-volatile memory (instrument operation history)
- to create editable list of the users responsible for working with instruments that can be saved and printed out
- to register (assign) instrument to a responsible user
- to save time, when the instrument was given to the user and returned
- to create and renew the radiation and chemical control information database on the basis of history events retrieved from the instrument
- to save, view and print out an individual history of each responsible user from the database
