Personal Radiation Detector PM1703MA-II

Category: Gamma PRDs

PM1703MA-II is a brand-new personal gamma radiation detector with improved search algorithm and NORM supress function. It 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. The instrument can be used both indoors and outdoors and is intended for everyday and/or emergency use by firefighters, military, police, and other first responding communities.

Operation Principle

As well as previous well-known modifications of PRD PM1703 Series, PM1703MA-II 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 gamma detector and the search algorithm based on background calibration is used. The Search Mode can be switched to “Mode 0…9”, which is designed mainly for monitoring of gamma radiation dose equivalent rate in the numerical range.

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

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 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 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.
