AT3509 personal dosimeter
Product model:
Brief description:This dosimeter is used to detect continuous and short-term X-ray, lambda ray dose equivalents and dose rate equivalents It can detect a wide range of dose rates, and has separate audio and visual alarm functions The microprocessor controls the operating mode, calculation, and displays data on the LCD with backlight and performs self-test After the dosimeter is turned off, the cumulative dose and its historical record are still stored in the memory This dosimeter is powered by a 30 x 30 x 15 cm aqueous phantom calibration and complies with ISO4037-3 international standard
