Product Description
The YD-100A Personal Alarm Dosimeter employs a metal compensation-type GM counter tube as its radiation detector. The instrument is characterised by high sensitivity,stable counting performance, and a wide measurement range,providing of X and γ radiation. A high-speed embedded microprocessor and a 1.8-inch TFT colour LCD are integrated into the device, and operation is facilitated by silicone keypad buttons. The instrument is intended for personal radiation dose monitoring and alarm functions in occupational exposure scenarios.
Features
• A high-speed embedded microprocessor is employed to ensure real-time processing of monitoring data and system status.
• A 1.8-inch TFT colour LCD with a user-friendly interface is provided for intuitive and efficient operation.
• A real-time 90-second dose rate measurement graph is displayed on-screen.
• Up to 512 dose rate alarm records are automatically stored; data are retained during power loss, and alarm logs are accessible for manual review.
• Alarm thresholds for both dose rate and cumulative dose are user-configurable.
• Dual alarm modes — vibration and audible alarm — are provided.
• Over-threshold alarm performance is characterised by short dead time and robust operation under high-dose-rate conditions.
• A GM counter tube fault detection and alert function is included.
• An integrated real-time clock displays year, month, and day; clock operation is unaffected by power-off.
