Shenzhen, China — CESTSEN announces the availability of the GM-16 Wristwatch Personal Dosimeter, a wearable radiation dosimeter with audible alarm built for continuous personnel dose monitoring in X-ray and gamma radiation environments. Worn like an ordinary wristwatch, the GM-16 places professional-grade dose measurement directly on the worker's body, delivering instant audible and visual warnings whenever dose rate, cumulative dose, or working time thresholds are exceeded.
Traditional badge-style and pocket dosimeters are frequently left in lockers, clipped to the wrong garment, or simply forgotten at the start of a shift. Because the GM-16 is worn on the wrist, monitoring starts the moment the strap is fastened and continues uninterrupted through the entire working day.
The GM-16 pairs an energy-compensated Geiger-Müller tube with an oversized backlit LCD, so technicians can read instantaneous dose rate and accumulated dose without stopping work or stepping into better light. Alarm thresholds for dose rate, cumulative dose, and working time are independently adjustable, allowing radiation safety officers to configure the instrument against local regulatory limits and internal site rules.
Measurement data can be exported to a computer through the magnetic charging head and data cable, giving dosimetry departments a straightforward path from field reading to formal record keeping. A fully charged unit runs for approximately 120 hours, covering multi-day field deployments and night shifts without a recharge.
