Ludlum Model 2221 Radiation Scaler/Ratemeter, Single Channel Analyzer It is attached to a 44-10 Scintillation detector for testing. This detector is available in another auction. Its very clean on the inside and works well!!! ? Digital Radiation Ratemeter with Built-In Scalers? Dual Analog Meter and Digital LCD Presentation ? Rich Array of Discrete Front Panel Controls ? Single Channel Analyzer ? Wide Range HV ? Overload Protection ? Supports GM, Proportional and Scintillation Detectors The Ludlum Model 2221 is a general purpose radiation ratemeter and scaler that provides a customary analog display for optimally viewing the count rate and rate of change through all possible four decades of display. It is accompanied by a digital LCD which can present either the count rate data or be switched over to read the scaler counts. What makes this instrument so well liked by experts is its rich array of logically arranged discrete controls on the front panel that permit precise control of the desired measurement. Control functions available include, decade range selection, scaler count time, power on/off, response setting, LCD analog/digital switch, PHA window switch, lamp, audio divide by, audio volume, count zeroing, scaler start/halt. The wide range high voltage supply supports a wide variety of detectors with additional threshold and window settings that facilitate switching between gross counts and the energy band. The instrument housing is cast aluminum with a separate battery compartment and accompanying metal handle. This design delivers industrial robustness, quality, capability, and versatility that is difficult to surpass anywhere. PART NUMBER: 48-2065 APPLICATIONS: radiation field analysis RATEMETER: provides a four-decade analog display that is operational any time the instrument is turned on, the ratemeter can also be presented on the accompanying LCD as a digital value when the LCD is switched to the "Dig. Rate" position SCALER: range from 0-999999 counts TIMER: switch selectable divisions of 0.1, 0.5, 1, 2, 5, 10 minutes or CONT (continuous) for manual timing CONCURRENT USE: scaler or digital ratemeter is active when not selected, allowing for concurrent use THRESHOLD: adjustable from 100-1000 (can be checked on display) WINDOW: adjustable from 0-1000 above threshold setting (can be turned on or off) GAIN: adjustable from 1.5–100 mV at a threshold setting of 100 OVERLOAD: senses detector saturation, indicated by “– – – –” on LCD display and meter going to full scale (adjustable depending on detector selected) HIGH VOLTAGE: adjustable from 400-2400 volts (can be checked on display) CONNECTOR: series "C" type (others available) METER FACE: 0–500 cpm, 50–500k cpm logarithmic scale (others available) DIGITAL DISPLAY: 6-digit LCD display with 0.5 in. (1.3 cm) high digits LCD BACKLIGHT: activated by LAMP switch AUDIO: built-in unimorph speaker with volume control AUDIO DIVIDE: toggle switch for 1, 10, or 100 events per click AUDIO JACK: for optional headset CONTROLS: Power Switch: On/Off Scale Selector Switch: x1, x10, x100, x1K, Log Response Switch: toggles between FAST (4 s) or SLOW (22 s) from 10% to 90% of final reading Meter Zero Pushbutton: to zero meter Audio Volume Knob: adjusts volume of audio output Audio Divide Switch: divides audio clicks by either 1, 10, or 100 Meter Lamp Switch: illuminates meter Window Switch: for selecting between wide open window counts or a narrower setting for viewing a specific energy band Scaler Count Time Selector Switch: 0.1, 0.2, 0.5, 1, 2, 5, or 10 minutes Count Pushbutton: starts or resets scaler count Count Hold Pushbutton: stops scaler count and leaves result in the display Scaler/Digital Rate Switch: selects which mode is presented on the LCD Test Buttons: battery, high voltage, threshold, window Calibration Controls: recessed screwdriver adjustments with calibration cover POWER: 4 each “D” cell batteries BATTERY LIFE: typically 250 hours with alkaline batteries (battery check on meter) SIZE: 9 x 4.3 x 10 in. (22.9 x 10.9 x 25.4 cm) (H x W x L) including handle WEIGHT: 5.5 lb (2.5 kg) including batteries NOTE: I will be on travel until 12/1/14 and will be unable to ship until then.
