Overview of MR-50L/X Online Radiation Monitor

The MR-50L/X Fixed Nuclear Radiation Monitor developed by CESTSEN (Shenzhen Wanyi Technology Co., Ltd.) is an advanced industrial-grade device designed for continuous real-time monitoring of alpha (α), beta (β), gamma (γ), and X-ray radiation.

It is widely used in environmental safety monitoring, medical radiation protection, customs inspection, industrial safety production, and radioactive material detection.

With high sensitivity and stable performance, the MR-50L/X provides reliable radiation level data for both environmental and industrial applications.

Low Power Consumption for Continuous Monitoring

One of the key advantages of the MR-50L/X radiation monitor is its ultra-low power consumption, making it ideal for long-term continuous operation.

Power supply: DC 12V–24V
Working current: 25–70mA
Power consumption: approximately 0.3W to 1.68W

This low energy design ensures stable 24/7 monitoring while significantly reducing operational power costs, making it suitable for large-scale distributed monitoring systems and IoT-based environmental networks.
