Give yourself and your customers an advantage. This affordable handheld radiation detection device is ideal for Homeland Security, detecting environmental / industrial contamination, education, and rock & mineral enthusiasts.

The DX-1 & DX-2 instantly indicate levels of Beta, Gamma, and X-Ray radiation by audible clicks from an internal speaker and by the compressed-scale meter. The DX-1 has an added feature: at higher radiation levels the speaker beeps, indicating elevated radiation levels. The beeping will begin above 10 mR/hr, intervals between beeps decreasing in relation to field strength, becoming a continuous alerting tone above 20 mR/hr. The DX-2 is useful for measuring higher levels (compacting several ranges into one scale) and features the ability to be recalibrated via a backside adjustment screw.

A single pushbutton activates the DX-1 and DX-2 only when needed, conserving battery power. An LED indicator alerts you of battery condition upon each use. Applications for the units are many and may include checking for environmental contamination, industrial, clinical, field, school classroom, home use, or wherever radioactive materials are present. Perfect for rock and mineral enthusiasts for its simplicity and convenience in identifying naturally radioactive rocks and ores, or for workers handling radioactive minerals, metals, and isotopes who are concerned about unknowingly bringing home contamination on their clothes and shoes.
