The SY-JB4000 intelligent X-γ radiometer is a specialized device designed for measuring the dose rate of X and gamma rays in various radioactive environments. Compared to similar instruments available domestically, this device offers a broader measurement range and improved energy response characteristics, making it more versatile and accurate for different applications.
This instrument is widely used in healthcare, environmental monitoring, metallurgy, oil and gas, chemical industries, radioactive laboratories, and commodity inspection, where accurate radiation monitoring and protection are essential. Its key features include high sensitivity, an extended measurement range, excellent energy response, single-chip control, and an LCD display with backlight functionality for easy reading in low-light conditions. The user-friendly interface allows for quick operation, and it comes with built-in memory to store 25 sets of dose rate data, enabling users to review past readings at any time.
Additionally, the SY-JB4000 supports cumulative dose measurement, with customizable alarm thresholds for dose rate, overload, detector faults, and battery low voltage. All components are housed in a durable stainless steel casing, making it ideal for field use.
