Multifunctional Nuclear Radiation X α β γ Rays Detector Electromagnetic Radiation Detection Device Real Time Monitoring 3.2inch LCD Backlight Display Units Adjustable Support 999 Data Record with Sound Alarm Function ( Item#: E21157 )

This product is one small type high sensitivity radiation dosage alarm device, mainly used to monitor the α, β, γ and X rays. It has the characteristics such as high sensitivity and accurate measurement. Widely applied in the environment where existing ionize radiation environment, human body accepted radiation dosage supervise and protection, such as family decoration, radiation shining manufacture enterprises, hygiene, nuclear lab, nuclear station, building materials, petroleum chemical, geology general investigation, used steels, industry flaw detection and others.

Features:
With high detection sensitivity, especially for environmental radioactivity  monitoring to detect traces of nuclear radiation.
Configured 3.2inch large LCD colorful screen, with backlight, 320*240 resolution, clear display definition, you can see the real time data clearly.
The dosimeter uses a Geiger-Muller counter tube to measure radiation, when each-ray passes through the G-M tube and causes ionization, the G-M tube generates a detection current pulse, and each pulse is detected by the electronic tube circuit and recorded as a count. (The displayed value of this dosimeter is the count value in the mode you selected.)
Due to the randomness of radioactivity, the count value detected by the dosimeter varies from minute to minute, so it is more accurate to take the readings within an average period of time, and the longer the interval is, the more accurate the average counts.
The detector is used to measure α, β, γ and X rays radiation, it is optimal for measuring small changes in radiation levels, and has high sensitivity for most commonly used nuclides.
Two working modes design, you can switch between ionization mode and electromagnetic mode according to your demands. 
The instrument support setting parameters, preset the alarm value and with sound alarm function, and 5 gears of volumes of alarm sound adjustable.
Temperature unit adjustable design, support conversion from ℃ or ℉ according to your preference easily.
Data recording interval setting design, you can set 10 seconds, 30 seconds, 60 seconds, 3 minutes, 10 minutes, 30 minutes and 1 hour data recording interval time.
Multifunctional design, with Chinese and English language switch function, time set, data delete and measurement units switchable function.
With shutdown time setting function, one button to select 10 minutes /30 minutes /1 hour /2 hours.
