The GM-R200 is a professional 4G gamma radiation monitor with GM-tube sensors, supports 25 probes, 7" touchscreen, Modbus RTU, and cloud platform access. Ideal for hospitals, nuclear sites, mines & environmental monitoring.

Monitor Gamma Radiation Anywhere, Anytime – With the Smart 4G Gamma Radiation Monitor GM-R200

In high-risk environments—from medical imaging centers to mining operations and border security checkpoints—continuous, remote-ready gamma radiation monitoring isn’t just a safety measure. It’s a strategic necessity.

Meet the GM-R200, a next-generation 4G gamma radiation monitor engineered by Wanyi Technology under the trusted CESTSEN brand. Combining proven Geiger-Müller detection technology with industrial-grade connectivity and cloud intelligence, the GM-R200 delivers unmatched coverage, reliability, and remote accessibility for regional radiation safety.

Why the GM-R200 Stands Out as a True 4G Gamma Radiation Monitor

✅ High-Sensitivity GM-Tube Detection

At its core, the GM-R200 uses rugged metal-walled Geiger-Müller (GM) tubes, optimized for accurate detection of gamma rays (as well as X-rays and hard beta particles). Multiple probe options allow customization for indoor, outdoor, or wall-mounted deployment.

✅ Monitor Up to 25 Zones Simultaneously

Unlike single-point detectors, the GM-R200 acts as a regional monitoring hub, supporting up to 25 independent radiation sensor probes. This enables comprehensive surveillance across:

• Hospital radiology departments
• Industrial NDT (non-destructive testing) zones
• Nuclear medicine storage areas
• Mine ventilation shafts or ore processing sites

Each zone is monitored, logged, and alarmed independently—ensuring no blind spots.

✅ Smart 7-Inch Touchscreen Terminal

The central unit features a bright, responsive 7-inch color touchscreen data logger with:

• Real-time display of dose rates, trends, and alarm status
• User-configurable alarm thresholds per sensor
• Built-in memory with adjustable data logging intervals
• Standard audio-visual alarm system for immediate hazard response

✅ Seamless Connectivity for Integration & Remote Access

The GM-R200 offers multiple communication options:

• RS232 serial output
• Modbus-RTU over RS485 – ideal for SCADA, PLC, or building management systems
• USB port for direct data export (CSV format)
• Optional 4G LTE module – transforms it into a true 4G gamma radiation monitor

✅ Cloud Platform: Monitor from Your Phone or PC

With the 4G-enabled GM-R200, all radiation data is automatically uploaded to CESTSEN’s secure cloud platform. Authorized users get:

• A dedicated login account (username + password)
• Live dashboards showing real-time gamma levels across all 25 zones
• Historical trend graphs and downloadable reports
• Email/SMS alerts when radiation exceeds preset limits

Perfect for facility managers, EHS officers, or regulators who need oversight without being on-site.

Trusted Across Critical Industries Worldwide

The GM-R200 4G gamma radiation monitor is deployed in:

• Hospitals & Dental Clinics – X-ray room leakage monitoring
• Mining & Rare Earth Processing – Natural background radiation tracking
• Industrial Radiography – Worker safety during pipeline or weld inspections
• Environmental Protection Agencies – Ambient gamma baseline studies
• Customs & Border Security – Detection of orphan radioactive sources
