Ludlum- Model 3277/1 Alpha-Beta Frisker

The Model 3277/1 is a wall-mount or desktop instrument that
can be used for frisking personnel or objects for alpha and
beta contamination. A large, color touch-screen displays alpha
and beta readings simultaneously, and dual tone click-audio
enables the user to easily distinguish between alpha and
beta contamination. Power is supplied by either an internal,
rechargeable battery or a 100 - 240 Vdc wall transformer.
Battery life is approximately 8 hours under normal usage.
The Model 3277/1 is supplied with either a wall mount or
a desktop mount. Mount type must be specified at time of
order. The instrument can be used with either scintillation or
proportional alpha-beta detectors. A list of compatible Ludlum
detectors is provided on the right.
