• Energy Compensated G-M Radiation Detectors

• Rugged

• 5 Decade Analog Ratemeter

Introduction

The Ludlum Model 5 is a gamma radiation exposure ratemeter equipped with two internally housed energy compensated G-M detectors that measure over the range of 0 to 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 5 decade range 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. The Ludlum Model 5 is an ideal instrument for Radiography surveys. The Model 5 is an ideal Radiography Ratemeter.
