Ludlum Model 14C Geiger counter offered.. 5 Attachment(s) I have a Ludlum Model 14C Geiger counter, and two Model 44-9 probes/detectors (detects alpha, beta, and gamma radiation). I'm employed in the Nuclear field, and I have personally used this unit. It works flawlessly, has a recent calibration, and as you can see from the pics, the battery check is good. Included is the counter instruction manual, detector (probe) instruction manual, and a check source to verify proper functioning. $250.00 shipping included. PM me if interested. Thanks, tnhighwayman LUDLUM MODEL 14C SURVEY METER DESCRIPTION/SPECIFICS: The Ludlum Model 14C survey meter was designed to meet nuclear medicine requirements. The Model 14C is similar to the Model 3, but with an internal energy compensated G-M detector. It can be used with one or more external GM or scintillation detectors for alpha, beta, or gamma detection up to 0-200 mR/hr. This additional internal detector creates fifth high range of 0-2000 mR/hr in addition to the four ranges covered by the external probe. It is used in hosptials, universities, power plants and regulatory facilities. Standard scale is 0-2 mR/hr with five counting ranges: x0.1, x1, x10, x100, and x1000. (Dual scale cpm & mR/hr are available on request). Two �D� cells provide over 200 hours of operation. The Model 14C is supplied as shown with built-in speaker. COMPATIBLE DETECTORS: G-M, scintillation METER DIAL:Typically 0 - 2 mR/hr and cpm, BAT TEST (others available ) MULTIPLIERS: X0.1, X1, X10, X100, X1000 LINEARITY: Reading within plus or minus 10% of true value with detector connected CONNECTOR: Series "C" (others available ) INTERNAL DETECTOR: Energy compensated G-M (used with X1000 scale only) ENERGY RESPONSE: Within plus or minus 15% of true value between 60 keV - 3 MeV (internal detector only ) THRESHOLD: 30 mV plus or minus 10 mV AUDIO: Built in unimorph speaker with ON/OFF switch (greater than 60 dB at 2 feet ) CALIBRATION CONTROLS: Accessible from front of instrument (protective cover provided ) HIGH VOLTAGE:900 volts THRESHOLD: 30 mV plus or minus 10 mV RESPONSE: Toggle switch for FAST (4 seconds) or SLOW (22 seconds) from 10% to 90% of final reading RESET: Push-button to zero meter POWER: 2 each "D" cell batteries (housed in sealed compartment that is externally accessible ) BATTERY LIFE: Typically greater than 1000 hrs.(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: 6.5" (16.5 cm)H X 3.5" (8.9 cm)W X 8.5" (21.6 cm)L WEIGHT: 3.5 lbs (1.6 kg) including batteries
