Alpha Monitoring
 Model 215 Frisker Station


This is a unique dual-purpose alpha contamination detection system that  can be used as both a stationary detector and a mobile frisker. When at a fixed station, the operator can use this innovative device as a stationary hand frisker, then simply remove it from the charging stand for use as any other mobile alpha frisker.

This convenient, integrated detector design requires no batteries, P-10 counting gas, or cables, giving the user complete freedom in performing frisking duties.
