LUDLUM Model 6 Gamma Ratemeter

The Model 6 is a gamma exposure ratemeter equipped with an internally housed, energy compensated GM detector that measures over the range of 0-10 Sv/ h ( 0-1000 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. INDICATED USE: Radiographers survey WORKING ENVIRONMENT: Splashproof shields for outdoor use DETECTORS: Internal energy compensated G-M tube ENERGY RESPONSE: Within plus or minus 15% of true value from 60 keV - 3 MeV SATURATION: In excess of 1000 R/ hr METER DIAL: 0 - 10 mR/ hr, BAT TEST ( others available) MULTIPLIERS: X1, X10, X100 LINEARITY: Reading within plus or minus 10% of true value with detector connected CALIBRATION CONTROLS: All controls are internal POWER: 2 each " D" cell batteries ( housed in sealed compartment that is externally accessible ) BATTERY LIFE: Typically 600 hours with alkaline batteries ( battery condition can be checked on meter ) METER: 2.5" ( 6.4 cm) arc, 1 mA analog type CONSTRUCTION: Cast and drawn aluminum with beige polyurethane enamel paint TEMPERATURE RANGE: -4° F( -20° C) to 122° F( 50° C) May be certified for operation from -40° F( -40° C) to 150° F( 65° C) SIZE: 9.5" ( 24.1cm) H X 3.5" ( 8.9cm) W X 8.5" ( 21.6cm) L WEIGHT: 4.4 lbs ( 2 kg) including batteries and detector
