Detailed introduction
RAD7 radon detector
According to the "Measurement Law of the People's Republic of China" and related regulations and technical requirements, the United StatesDURRIDGE's electronic radon meter RAD7 has been certified and obtained the meter type approval certificate of the People's Republic of China.
Features:
l Radon radiation source finder/Radon gas continuous detector
l Measured radon and thorium can be displayed in the form of spectral curves
l It is the electronic radon detector with the fastest response and the shortest recovery time on the market. It is a portable detector that integrates continuous monitoring of radon gas and detection of radon radiation sources.
l The operation is simple, just follow the prompts of the microcomputer, the measured radon and thorium will be displayed as a spectrum curve, and the data can be output with an infrared printer.
l Meet the U.S.EPA operating standard of 4 pCi/L for 1 hour
l Displays and prints continuously updated radon level values from start to test
l Test results can be displayed on the computer, printed out, and data downloaded
l The spectrum curve shows the accuracy of the instrument in field operation.
l Spectrum Reader:The alpha distribution histogram verifies the radon/thorium content and also verifies the correct operation of Rad7. Correct measurement of alpha particle energy can be used as an energy signature to distinguish the alpha particles of radon and thorium from other alpha particles of the same number.
l Data confidentiality:The "Test Lock" command ensures that your data is not tampered with on the machine
RAD7 alpha spectrum
l Automatic mode: This setting starts using detection mode,Automatically switches to normal mode after 3 hours
l Fast low value detection: in continuous measurement mode,The RAD-7 measures radon at an EPA operating level of 4 pCi/L over 1 hour with a standard error of 2%. Since RAD-7 actually has nobackground design, so it is more sensitive than other electronic radon detectors and can easily measure as low asRadon at 0.1pCi/L level
