HRD-4 Wristwatch-style Personal Dosimeter with Cumulative Dose Equivalent 0.0 μSv-9999 mSv and Measuring Range 0.10 μSv/h-50mSv/h
The HRD-4 wearable (wristwatch-style) personal dosimeter is designed for measuring personal dose equivalent caused by X and γ radiation. This device is particularly suitable for medical applications in interventional radiotherapy and various industrial radiation environments.
Controlled by a low-power single-chip microcomputer, this dosimeter features LCD drive display, measurement data storage, parameter setting, detector fault alarm, battery voltage detection, over-threshold sound and light alarm, and charging capabilities.
Applications include radioactive medical treatment, industrial non-destructive testing, radioactive isotope application, occupational disease prevention, military units, nuclear power plants, and monitoring of surrounding areas in radioactive workplaces.
