Radiography Ratemeter - Model 5
The Model 5 is a gamma exposure ratemeter equipped with two internally housed, energy-compensated GM detectors that measure over the range of 0-20 mSv/h (0-2000 mR/hr). The aluminum cast 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 controls include a rotary switch for selecting the five display ranges and instrument shut-off, an audio on/off switch, a fast/slow response switch, and push-buttons for count reset and battery test. The Model 5 is a complete turn-key system and includes two "D" cell batteries.
