Usage Tips:[Geiger- Counter ] The -886A nuclear radiation meter revamps the standard radiation detection with an energy compensation tube detector to enhance sensitivity. Specifically designed to accurately detect ionizing radiation intensity including beta particles, gamma rays, and x-rays within the energy range of 48keV-1.5Mev less than equal 30% (for 137Cs), it becomes a reliable for radiation measurement. [Multifunctional Nuclear Radiation Meter] Apart from measuring radiation intensity, this innovative device doubles as a monitor for temperature and humidity. It exhibits current radiation value, maximum value, and average value in different geographical areas on its display, alongside a user-integrated dose alarm value to to your measurement needs and reliable readings. [Flexible Unit Conversion] This cutting-edge nuclear radiation meter comes with 5 built-in dosage units switchable between Sv/h, Gy/h, mR/h, , and cpm. Capable of detecting ray types such as -rays, x-rays, and -rays, it is an all-inclusive gadget for all your radiation detection tasks. [Intelligent Alarm System] With an integrated alarm system that operates in three ways - light, vibration, and sound, the -886A nuclear radiation meter is designed to alert you in different scenarios. You can adjust the current/cumulative dose alarm value and reset the cumulative dose through the alarm settings for a customized experience. [Broad Application Spectrum] From nuclear power plants, geological surveys, to radiology departments and home decor radiation, this nuclear radiation meter is your go-to device for detecting ionizing radiation and displaying the dose. It fits for diverse environments including industries, radiation labs, iron mines, and inspection vehicles amongst ot Please note:There is a slight color differenceor difference in kind, it does not affect the use, please do not mind, thank you!
