FJ2000 Portable Geiger Counter Dosimeter — Handheld X & Y Ray Radiation Detector, Personal Dose and Dose-Rate Monitor

The FJ2000 personal dosimeter is an intelligent, pocket-sized instrument built on single-chip microcomputer technology, offering robust functionality in a compact handheld package. As a Geiger counter nuclear radiation detector, it is primarily used to monitor X ray and Y ray and provides direct readings of personal cumulative dose and real-time dose rate. Alarm thresholds can be fixed or preset within the measurement range; when a threshold is exceeded or blocked the device issues both audible and visual alarms to alert staff. The unit performs simultaneous measurement of personal cumulative dose and dose rate, and includes multiple alarm functions. It delivers high sensitivity, stable and reliable operation with low power consumption, and its small size makes it easy to carry. Typical applications include industrial non-destructive testing, nuclear power plants, nuclear submarines, isotope use, and hospital cobalt treatment among other fields.
