Electronic Dosimeter PM1211


A new PM1211 Series of gamma-radiation dosimeters is designed to replace well-proven electronic dosimeter PM1203M. 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.

PM1211 is the best instrument for professional and non-professional use!
* The device is at the production stage.


Operation Principle:

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.
