Polimaster Innovating radiation detection technologies since 1992

Personal Radiation Monitor/Dosimeter PM1605BT

Electronic Dosimeters of PM1605 series are designed to withstand extreme environmental hazards such as limited visibility, raised noise, high temperatures, exposure to sea water, shock and falls. Metal enclosure is resistant to influence of temperature up to 100°С for 2 minutes, and to water immersion (including salt-water) at the depth of 1 meter for not less than 2 hours. Control panel with two big buttons allows the using of protective gloves while operating the instrument. PM1605BT and PM1605-BT are equipped with Bluetooth 4.0 Low Energy Module and can transmit data in real time via smart phones application.

Instruments are recommended for personal radiation protection of first responders, HAZMAT teams, civil defense, firefighters and the other divisions who deal with radiological emergencies.

Operation Principle

Electronic dosimeters of PM1605 series are designed to measure ambient dose equivalent rate and ambient dose equivalent of X-ray and gamma radiation. Instruments are able to search, detect and localize radioactive sources, alert the user with audible, visual and vibration alarms, transmit stored data to PC or via smartphone.

Dosimeters have large and easy-to-read backlight LCD display, metal enclosure which is resistant to influence of temperature up to 100°С for 2 minutes, and to water immersion (including salt-water) at the depth of 1 meter for not less than 2 hours, easy-to-use two-buttons panel. Measurements can be displayed both in R for the USA or Sv for Europe.
