NR-850 Handheld Portable Nuclear Radiation Detector LCD Display Household Radioactive Tester Geiger Counter β Y X-ray Detection Sound Vibrations Light Triple Alarm Practical Nuclear Radiatio

Nuclear radiation is a problem that each one needs to pay attention to, because it may bring some serious consequences, such as disease or even cancer. Our nuclear radiation detector can help you to detect nuclear radiation well, so if you need it, come and try it.

Features:
Using LCD display, working status of nuclear radiation instrument is clear on display, and you can quickly and accurately read data you need.
With function of automatically storing cumulative dose, even if is suddenly cut off, data will not be lost and can be stored for a long time.
There are three alarm methods: sound, light and vibration, which can better remind you and give you a better experience.
Hand-held portable design, easy to carry and store, you can put it in your pocket for carrying.
