The SY-JB4000 intelligent х-γ radiometer is a special instrument for monitoring the radiation dose rate of х and γ ray in various radioactive workplaces. Compared with domestic similar instruments, the instrument has a larger dose rate measurement range and energy response characteristics. The instrument is widely used in sanitary, environmental protection, metallurgy, petroleum, chemical, radioactive laboratory, commodity inspection and Other occasions where radiation environment and radiation protection testing is required. Features: high sensitivity of the instrument, large measuring range; good energy response characteristics, single-chip control, LCD liquid crystal display; backlight function liquid crystal display, backlight function; easy to operate, built-in 25 sets of dose rate storage data, you can check the dose rate at any time, the cumulative dose can be Measurement with dose rate threshold alarm, dose rate overload alarm, detector fault alarm, battery undervoltage alarm function all stainless steel housing, suitable for field operation technical indicators: 1, detector: φ30 × 25mm, NaI (TL) 2, sensitivity: 1μSv /h≥350cps3, quantity threshold: 35Kev4, quantity range: dose rate: 0.01～200.00μSv/h cumulative dose: 0.00μSv～9999.99μSv5, energy range: 48Kev～3Mev6, energy response: 48Kev～3Mev≤±30% (relative 137Cs) 7, relative basic error: ≤ ± 10% 8, measurement time: 1, 5, 10, 20, 30 seconds can be adjusted 9, alarm threshold: 0.25, 2.5, 10, 20 (μSv / h) 10, reading Display: dose rate: μSv/h, μGy/h, μR/h selectable cumulative dose: μSv Count rate: CPS11, power consumption: power consumption of the whole machine ≤160mW (excluding display backlight power consumption) 12.
