I bought one and used it everyday for continuous monitoring. Radon detector, Safety Siren Pro Series 3. It's very nice. Also saved me money on Radon inspection. Very accurate compared to professional results. http://www.amazon.com/Safety-Siren-Pro-Detector-HS71512/dp/B000CEAY64
【在 T**J 的大作中提到】 : 自动显示数字的系统,做梦吧?

LED digital readout is pretty normal nowadays ah Many houses around here have it running 24/7, because, well, there are so many granite quarries around Boston, and they are all rich in radon.
