Upgraded PRD PM1703xx-II Series have improved CsI(Tl) detector characteristics and fully comply with ANSI N42.32-2016.
The extended measurement range is enabled by the installed new CsI(Tl) detector with a semiconductor photomultiplier (SiPM).
* Instruments of PM1703xx-II Series were successfully tested in ORNL.
PM1703MO-II BT has two built in detectors (CsI(Tl) and Geiger counter) and such competitive features as improved search algorithm and NORM supress function, extended DE and DER measurenet ranges, high sensitivity, compact size, user-friendly interface, low-energy operation, waterproof and shockproof case.
Instrument is intended for everyday and/or emergency use by firefighters, military, police, and other first responding communities.
Operation Principle
Instruments of PM1703xx-II Series were successfully tested in ORNL.
- The instrument has increased sensitivity due to two built in detectors: the highly sensitive CsI (Tl) scintillation detector for a fast response and location of radioactive sources, as well as energy compensated Geiger-Muller detector for high dose rate range and accurate measurement.
- The suppress NORM algorithm allows excluding alarm signal when the natural gamma background value increases and Naturally Occurring Radioactive Materials (NORM) are detected.
- The instrument displays the current level of gamma radiation background in numerical range from 0 to 9, that simplifies visualization of the radiation dose rate for the user.
- All the operations history is stored in the instrument non-volatile memory, protecting the data even when the battery is removed. The stored data can also be transferred to the personal computer via USB interface.
- The instrument is equipped with Bluetooth channel and can exchange data with smartphones, that's very important for the day-to-day operation.
- The instrument can be used both indoors and outdoors.
Supress NORM algorithm
The suppress NORM 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 case the other radionuclides types (IND, NUC, MED) are detected, red indication light and audio alarms are activated.
Communication with smartphone
PM1703MO-II BT can transfer data via Bluetooth® 4.0 to smartphones based on Android (version 6.0 and higher) with "Polismart®" Mobile App. Free Mobile App is available for AndroidTM mobile devices and can be downloaded from Google PlayTM.
Options
- PM1703MO-II BT can be equipped with holster that provides additional protection in various weather conditions. It can be also fixed on the waist belt using belt loop.
- PM1703MO-II BT can be equipped with telescopic extension pole for operating in remote and hard-to-reach areas.
