Combined Chemical Agent and Gamma Radiation Detector PM2012M
PM2012M 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. PM2012M 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.
PM2012M/MA/MB can be used by first responders, police officers, customs and border patrol services, HazMat Teams.
Operation Principle
PM2012M consists 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 
Optional Accessories
