Features 1、2.4 Inch HD LCD Display: This nuclear radiation detector adopts 2.4 inch HD LCD display, which is clear, beautiful and easy to read, so you can get a clear picture of the radiation situation in the environment. 2、Dual Alarm Alert: This nuclear radiation detector has a triple alarm alert, beyond the alarm threshold, sound, light the dual alarm alert, display real time values and cumulative values, easy to view the value changes in a timely manner. 3、Multifunctional: This radiation monitor meter a professional detection of ionizing radiation (rays, Y rays and X rays) strength of the tally instrument. An inflatable tube or chamber is used as a probe, and when a certain range of voltages is applied to the probe, whenever a pair of ions is produced by ionization of a ray in the tube, it can be amplified to produce an electrical impulse of the same magnitude, which is recorded by a connected electronic device, thus making it possible to measure the number of rays per unit of time. 4、Wide Application: This nuclear radiation dosimeter has a wide range of applications and can be used for nuclear wastewater detection, X, Y, beta ray, seafood nuclear radiation detection, medical nuclear radiation detection, marble radiation detection, food nuclear radiation detection. 5、Excellent ABS Material: This portable radiation detector is made of excellent ABS material, which is sturdy and abrasion resistant, not easy to be damaged, and has a long service life.
