JB4000 Intelligent X and γ Radiometer

brief introduction
The JB4000 (A) intelligent X-ray radiometer is a specialized instrument for monitoring X-ray and gamma radiation dose rates in various radioactive workplaces. Compared with similar domestic instruments, this instrument has a larger dose rate measurement range and energy response characteristics.

This instrument is widely used in places that require radiation environment and radiation protection testing, such as hygiene, environmental protection, metallurgy, petroleum, chemical, radiation laboratory, and commercial inspection.

JB4000 is an environmental level monitoring instrument with a measurement range of 0-200 µ Sv/h; JB4000 (A) type is a protective level monitoring instrument with a measurement range of 0-1500 µ Sv/h.
