Model 6

Geiger Counter

Part Number: 48-1676

Features

• Range: 0 to 10 mSv/h (0 to 1000 mR/hr)
• Splashproof
• Energy Compensated GM Detector
• Overload Protection
• Rugged
• 3-Range Analog Ratemeter

The Model 6 is a gamma exposure ratemeter equipped with an internally housed, energy compensated GM detector that measures over the range of 0 to 10 mSv/h (0 to 1000 mR/hr). The cast aluminum instrument housing with its separate battery compartment and accompanying metal handle offer an industrial robustness and quality that promote long lasting protection and instrument life. The front panel offers a single rotary switch for selecting the three-decade range, instrument shut-off, and battery test. The Model 6 is a complete turn-key system and includes two "D" cell batteries.
