PM1703GNA-II models are gamma-neutron PRDs equipped with a high-sensitive scintillator for measurement of the personal dose rate up to 300 µSv/h. While ensuring high-performance detection for any scenario, PM1703-II PRD provides confidence in personal safety by continuously monitoring the measured dose equivalent rate and alerting the user with visual, audible and vibration alarms when the pre-set radiation thresholds are exceeded.
Operating history is stored in the instrument‘s non-volatile memory (up to 2000 data points), protecting the data even when the battery is removed. The stored data can also be transferred to a PC via USB. Storing data format is designed to meet the ANSI N42.42.
The PRD features a dedicated operation mode “Mode 0…9” specifically designed for monitoring gamma radiation dose rate within a numerical range. This mode is particularly user-friendly, making it easier for non-professionals to understand and navigate.
Polimaster PRDs offer a significant advantage with their NORM suppression algorithm. This algorithm differentiates alarm signals when there is an increase in natural gamma background values and detection of Naturally Occurring Radioactive Materials (NORM). When NORMs are detected, a green indication light is displayed. However, if other radionuclide types (IND, NUC, MED) are detected, a red indication light and sound alarm are activated. This feature ensures clear and distinct indications based on the specific type of radiation detected.
