The Model 3277/1 can be used for frisking personnel or objects for alpha and beta contamination. Ludlum developed this wall-mount or desktop instrument with a simple layout and high usability.

The 3277/1 has a large, color touch-screen that displays alpha and beta readings simultaneously. The dual tone click-audio enables the user to easily distinguish between alpha and beta contamination. It uses an internal, rechargeable battery or a 100 – 240 Vdc wall transformer.
