  • Product Description

    The DX-1 Radiation Monitor detects Beta, Gamma, and X-radiations.  The counter emits audible clicks from its internal loudspeaker and registers radioactivity on adx1metertn.jpg compressed scale analog meter (see right) up to 10 mR/hr, compacting several ranges into one, available at a glance.

    In addition to the audible clicks, at high radiation levels, the speaker beeps, indicating obvious danger. The beeping begins at about 20 mR/hr, with intervals between beeps decreasing in relation to field strength, becoming a continuous tone at 200 mR/hr.  Play this sound file.

    The DX-1 includes an easily replaceable, yet long-lasting 9 volt battery.  A single pushbutton activates the DX-1 only when needed, as seen in the picture above, and thus conserves battery power. An LED indicator reassures you of battery condition upon each use.  The DX-1 is ruggedly constructed and continues to operate in a saturation environment.

    The DX-1 is a good Pocket Geiger Counter - affordable, simple to use, and all that is needed for a basic determination of whether or not something is radioactive.  Purchase the DX-1 above, or if you would like to consider the similar, but higher ranging DX-2 model, choose that from Related Products.

    This item typically ships within 1 business day.
