Operation Principle
The PoliGate™ Vehicle series may have a modular design and are available in one-pillar or two-pillar configurations, adaptable height and width according to customer requirements.
This series of RPMs comply with the IEC 62244:2019 standard.
Equipped with highly sensitive scintillation detectors, the RPM can continuously detect and measure ionizing radiation in real-time. This means that as soon as radiation is present, the device swiftly captures and analyzes the data, providing immediate feedback.
The RPM is easy to operate and maintain, requires minimal training, and is supplied with user-friendly software that provides real-time data and alarms.
The connection to an operator computer or compatible external devices allows to effortlessly transmit the recorded radiation measurements for further analysis and monitoring. The real-time measurements are displayed in an easily readable format, ensuring a quick and accurate assessment of the radiation environment. This data transfer capability ensures that all measurements are logged and stored for comprehensive record-keeping and future reference.
