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. Battery life is approximately 8 hours under normal usage. This model is supplied with either a wall mount or a desktop mount. The instrument can be used with either scintillation or proportional alpha-beta detectors.
