The GM-W100 wristwatch personal dosimeter is suitable for radiation dose equivalent measurement in a wide range of professional environments:
Always-On Protection: The wristwatch form factor ensures the dosimeter is always on the wearer's body during work hours — no risk of forgetting to clip on a badge-style dosimeter. This continuous monitoring provides more reliable dose tracking compared to traditional pocket or clip-on designs.
Dual Alarm Security: With independent alarm thresholds for both instantaneous dose rate and cumulative dose, workers receive immediate audible and visual warnings before exposure limits are reached. The working time alarm adds an additional layer of safety for time-restricted operations.
Professional-Grade Accuracy: The energy-compensated GM tube detector delivers ≤ ±15% relative intrinsic error (¹³⁷Cs), compliant with international radiation protection standards. The wide energy response range (50 keV to 1.3 MeV) ensures accurate measurements across common medical and industrial radiation sources.
Certified Quality: CESSTEN instruments hold CE, CMA, and CNAS certifications, meeting rigorous international quality and safety standards. Each unit is calibrated and tested before shipment from our Shenzhen manufacturing facility.
Custom configurations including modified dose rate ranges, specialized alarm thresholds, and branded packaging are available upon request. Contact the CESSTEN sales team for a tailored quotation and technical consultation.
