- 48 mm Geiger Muller tube counter for nuclear radiation detection, mainly for Beta, Gamma, and X-Ray. Detection range: 0.08 uSv to 50 mSv. This provides broad screening and higher exposure monitoring in a single device. - White OLED screen for clear readings, visible at night for quick checks in low light or dim environments. - Compact and lightweight design with a pen clip for easy wear or pocket carry. Standby up to 50 hours for extended field use. - Dual alarm modes with sound and flash. Alarm threshold is adjustable by key to suit different environments and safety requirements. - Practical applications: - On-site safety surveys in laboratories, medical facilities, or industrial settings to monitor ambient radiation levels. - Field radiation surveys during construction, maintenance, or incident response where portable monitoring is needed. - Personal monitoring during travel or routine checks in areas with potential radiological exposure. This device emphasizes reliable performance, portability, and user-friendly operation for quick, actionable radiation assessment.
