The DX-1 Radiation Monitor can instantly detect beta, gamma and x-ray radiation. This monitor emits audible clicks and while registering radiation levels on a compressed scale analog meter. At high radiation levels above 10 mR/hr, the speaker will beep, indicating dangerous radiation levels. The DX-1 has an LED indicator for battery usage and comes with an easily replaceable 9 volt battery.
DX-1 Radiation Monitor Specifications:
Visual and audible warnings are made by clicks from an internal speaker and given by the compressed-scale, analog display. An audible alarm is triggered when radiation levels exceed 10mR/hr, increasing in frequency in proportion to the radiation level. An LED indicator alerts you that meter is on and of battery condition upon each use.
