PCR-300 RC, PCR-300 specifications

The Honeywell PCR-300 and PCR-300 RC are advanced portable radiation detectors designed to meet the needs of various industries, including emergency response, nuclear power plants, and environmental monitoring. Known for their reliability and accuracy, these devices are essential in a world where radiation monitoring is increasingly crucial for safety and regulatory compliance.

The PCR-300 features a compact and lightweight design, making it easily transportable. This portability does not compromise its robust construction and ability to withstand harsh environmental conditions. With an intuitive user interface, the device allows users to operate it effectively even with minimal training.

One of the standout features of the PCR-300 is its dual-range detection capability. It can accurately measure gamma radiation levels across a wide spectrum, providing real-time data to users. The instrument is equipped with a scintillation detector, which enhances its radiation sensitivity, allowing for the detection of low levels of radiation that other devices might miss.

Additionally, the PCR-300 RC model includes advanced communication capabilities, which enable users to transmit data wirelessly. This feature is particularly beneficial for teams in the field, as it allows for instant data sharing and collaboration, enhancing situational awareness during critical missions.

Another notable technology incorporated into the PCR-300 series is its built-in GPS function. This feature facilitates the tracking of radiation readings along with geographical locations, providing crucial context during surveying or emergency response. The device is designed to store measurement data, allowing for easy retrieval and analysis after the mission is complete.

Durability is also a focus in the design of the PCR-300. The device is built to resist water and dust ingress, adhering to high IP (Ingress Protection) ratings. This ensures that the device can operate effectively in various environmental conditions without fear of damage.

Battery life is another important aspect of the PCR-300, with an extended operational time that allows users to conduct lengthy assessments without frequent recharging. The intuitive display screen provides clear visual feedback, showing real-time radiation levels, battery status, and operational alerts.

In summary, the Honeywell PCR-300 and PCR-300 RC are sophisticated tools equipped with cutting-edge technology. Their combination of portability, dual-range detection, GPS functionality, and advanced communication features make them indispensable for professionals tasked with monitoring radiation in diverse settings. With a focus on durability and extended battery life, these devices ensure that safety and efficiency are always prioritized in radiation detection efforts.
