Electronic Dosimeters of PM1211 series provide a new feature of automatic calculation and display of the countdown of safe stay near an ionizing radiation source.
Dosimeters measure the ambient dose equivalent rate (DER) and dose equivalent (DE) of gamma and X-ray radiation, record data in non-volatile memory, have visual, audible and vibration alarms, communicate PC via USB and exchange data with mobile devices via Bluetooth 4.0 LE (models PM1211-01, PM1211-03). Modifications PM1211-02 and PM1211-03 are equipped with GPS module.
Electronic dosimeters of PM1211 Series are recommended for officers of customs and border patrol, transport organizations, personnel of nuclear power facility, radiological and isotope laboratories, offices of Ministry of Emergency Response, police, radiation safety services of other ministries and departments and a wide range of people dealing with radiation in everyday life.
Dosimeters are designed for continuous measurement of DER and DE of X-ray and gamma radiation. Instruments produce audible, visual and vibration alarms if the preset DE and DER thresholds are exceeded, save measurements history in non-volatile memory, work up to 24 months from one battery (mod.PM1211 and PM1211-01) and up to 12 months from rechargeable LIR2450 battery (mod. PM1211-01 and PM1211-03). Additionally, dosimeters have the function of indication of current time (hours, minutes, seconds), date (date, month, year) and air temperature on the liquid-crystal display (LCD).
Instruments are easy in operation, have user-friendly interface, so can be used by untrained users.
When DER threshold is exceeded, PM1211 automatically switches to the mode and displays the DER value and countdown of safe stay in the current radiological environment.
The countdown is displayed in days, hours and minutes, so the user can assess the level of radiation danger and quickly make a decision about further actions – move away at a safe distance.
