Feature:1. This handheld nuclear radiation detector adopts a minimalist appearance design, is portable in size, and easy to carry. The test is started automatically after power on, easy to operate.2. Adopts high precise Geiger-Muller tube radiation detector and high-end low-power intelligent terminal chip, which provides high sensitivity radiation detection capability and data processing function with high detection accuracy.3. It is mainly responsible for monitoring the radiation of X, γ, and β rays in various radioactive working areas.4. White OLED display design, clearer display, you can read the detection data clearly and easily, and you can get results in time.5. Measure the dose rate in real time, and at the same time record the cumulative dose and the average value of the interval. Measurement error is small, can be over the national measurement standard.6. Over-dose alarm function, sound and light alarm. Dose rate alarm threshold, measurement alarm threshold can be set by yourself.7. Built-in rechargeable lithium battery, can fully meet the long-lasting test. The display can continue to measure after auto-sleep. Sensor failure function (the display shows \"Device Fault\").8. Wide applications, it can be widely used in nuclear power plants, accelerators, the iron \u0026 steel industry, the chemical industry, isotope applications, radiology laboratories, and ambient monitoring of nuclear facilities.​Specification:HFS-A3 x, β, γ radiometer adopts high precise Geiger-Muller tube radiation detector and high-end low-power intelligent terminal chip, which provides high sensitivity radiation detection capability and data processing function with high detection accuracy. It is equipped with white OLED screen, the tested data can be visualized seen at night. There are two alarm modes: sound and flash, and the alarm threshold can be set by yourself. Small size, fast response time, and wider dose measurement ranges of professional wearable instruments. It can be widely used in environmental protecting, metallurgy, flaw detection, food and other industries, as well as the detection of excessive radiation in the human environment.Features:This handheld nuclear radiation detector adopts a minimalist appearance design, is portable in size, and easy to carry.
