Easily Check for Radioactivity with the Handheld DX-1 Geiger Counter
Portable DX-1 Geiger Counter instantly indicates the presence of Beta, Gamma or X-Ray radiation by audible clicks from an internal speaker and by the compressed scale meter. Speaker beeps above 10 mR/hr. and the beep becomes a continuous tone above 20 mR/hr. Incorporates the detection tube into its specially designed high-impact case as a single, complete, handheld unit. Just one push-button control activates the unit—no switches are required, as the calibrated meter utilizes several ranges in a single one. Accuracy is ±20 percent. Operates 50 hours on one 9V battery. LED indicates battery level upon each use.
