FJ-3602II Digital Gamma X-ray Radiation Survey Meter with Data Storage & Alarm Function
PRODUCT PROFILE
The FJ-3602II X and γ Radiation Survey Meter is a specialized instrument for monitoring X and γ-ray radiation dose rates in various radioactive workplaces. Compared with similar domestic instruments, this device features a wide dose rate measurement range and superior energy response characteristics. This series of instruments offers measurement functions including dose rate, cumulative dose, and CPS, making the device more versatile and highly praised by users, particularly those in health supervision departments. It utilizes advanced microcontroller technology and an 8-stage photomultiplier tube detector. Through effective energy compensation, the instrument achieves both a broad measurement range and excellent energy response characteristics.
