RadWall-E | Area Radiation Monitor is an Ethernet-enabled, all-digital area radiation monitor covering a wide range of gamma and X-ray radiation.

SKU: ARM-WAL-E Category:


RadWall-E | Area Radiation Monitor is a next-generation all-digital area radiation monitor that combines three functions in one:

  • Alarm and display unit
  • Built-in scintillation detector
  • Ethernet-enabled monitor

RadWall-E | Area Radiation Monitor uses a high-performance YSO scintillation crystal combined with a state-of-the-art SiPM (YSO+SiPM) and multi-voltage threshold (MVT) algorithm to detect a wide range of radiation doses.

RadWall-E| Area Radiation Monitor has high detection accuracy, high sensitivity, and fast response, as well as other significant advantages.

RadWall-E | Area Radiation Monitor communicates with a radiation monitoring network via Ethernet for data management. Proportional, real-time detection and measurement provide meaningful readouts that focus on real-world applications.

The fast response and wide dose rate range maximize the safety of your team. The high-contrast OLED display provides a clear indication of dose rate.

RadWall-E | Area Radiation Monitor is an alarm and display unit (ADU), providing detection and measurement with an internal scintillation detector.
