A great way to measure and log radioactivity! Watch as background levels fluctuate over the course of a weekend, or bring objects up to the sensor to see if they are emitting more than background. Compact G-M tube sensor plugs into your computer’s USB port. Intuitive software allows monitoring of BETA and GAMMA radiation levels right away and shows graphically how the levels are changing over time.
Data is collected every 3 seconds and is date and time stamped. Display as CPM, mR/hr, or uSv/hr. Averaging time is selectable from 15 seconds to 10 minutes. No batteries or external power required. Audible event beep (can be disabled in software). There is even an audible alarm which you can set to go off at any level. Includes software CD and cable. Easy set-up. 1 year warranty. Made in USA. Now look at the low price!
Must be connected to computer to work, not a stand alone device.
