Model 215

Alpha Frisker Station

Part Number: 48-3695

Features

• Dual Purpose Alpha Frisker & Hand Monitor Station
• Detector Operates Independent of Its Stand
• Simple to Use
• No Cables or Gas Required

Ludlum Model 215 is a unique dual-purpose alpha contamination detection system that can be used as both a stationary detector and a mobile frisker. When alongside a glovebox, 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 P-10 counting gas or cables, giving the user complete freedom in performing frisking duties. The large area, air proportional detector has built-in electronics, display, and NiMH rechargeable batteries that allow it to be operated for at least 3 hours before needing to be recharged. The charging stand interfaces to a PC to facilitate setting parameters and running high voltage plateaus via an optional application program.
