- Professional Radiation Dose Alarm Instrument: uses a GM counter tube to monitor X, Y, and beta (β) rays with high sensitivity and accurate measurement. - OLED display: clearly shows the instantaneous dose, average dose, and cumulative dose rate, with good visibility in low light. - Easy to Use: one-button startup and automatic test; audible and visual alarm if the test exceeds the limit. - Rechargeable and Reusable Battery: built-in lithium battery power supply, with power-saving design for durability. Applications and scenarios - Laboratory safety and monitoring in environments with X, Y, and beta radiation sources, ensuring real-time awareness of exposure levels. - Field radiography, imaging, and radiological inspections where portable dose monitoring is needed during operation. - Industrial nondestructive testing, research experiments, or educational settings requiring reliable dose monitoring and alarms to manage exposure.
