Personal Radiation Detector PM1703MA-II (PM1703®)

Category: Gamma PRDs

PRD PM1703MA-II  (PM1703®) is a brand-new personal gamma radiation detector, which has such competitive features as compact size, user-friendly interface, low-energy operation, waterproof and shockproof case combined with extremely high sensitivity.

Instrument continuously monitors the environment for radiation and alerts the user with a visual, audio and/or vibrating alarm if a radiation source is detected or any of preset radiation thresholds are exceeded.

PM1703MA-II  (PM1703®) is designed to detect, search, and locate gamma radioactive sources.

Operation Principle

As well as previous well-known modifications of PRD PM1703 series (PM1703®) , PM1703MA-II  (PM1703®) continuously monitors the environment for radiation, evaluates dose equivalent rate (DER) and alerts the user with a visual, audio and/or vibrating alarm if a radiation source is detected. The readings of the instrument are displayed in counts per second for both neutron and gamma detectors and the search algorithm based on background calibration is used. The Instrument has “Mode 0…9” , which is designed to display the current level of gamma radiation background in the form of digits from 0 to 9. 

All operations history is stored in the instrument non-volatile memory (up to 1000 data points), protecting the data even when the battery is removed. The stored data can also be transferred to the PC via USB interface. Storing data format is designed to meet ANSI N42.42.


PM1703MA-II - basic model

PM1703MA–II BT - additionally to the functions of the basic model, is equipped with Bluetooth radio channel that enables the function of smartphones communication

PM1703MA–II MBT - differs from the basic model by extended range of DER measurement, presence of DE measurement mode and Bluetooth radio channel

Supress NORM algorithm

This algorithm allows excluding alarm signal when the natural gamma background value increases and Naturally Occurring Radioactive Materials (NORM) are detected. If NORM are detected - green indication light is given. In the case the other radionuclides types (IND, NUC, MED) are detected, red indication light and sound alarm are activated.


Optionally PM1703MA-II (PM1703®) can be equipped with holster that provides additional protection for the instrument from weather, dust and occasional drops. It can be also fixed on the waist belt using belt loop.

Communication with smartphone

PM1703MA-II BT and PM1703MA-II MBT can transfer data via Bluetooth® 4.0 to smartphones based on iOS (version 7.1.1 and higher) and Android (6.0 and higher) with  Polismart® Mobile App. Free Mobile App is available for iPod® touch, iPhone®, iPad®(iOS) and for AndroidTM mobile devices and can be downloaded from App StoreSM or from Google PlayTM.
