Model 3000

Digital Survey Meter

Part Number: 48-4035

Features

Large, Backlit, Easy-To-Read LCD Screen
Auto-Ranging
RATE, MAX, and COUNT Modes of Operation
Splash-Resistant Construction for Outdoor Use
All-Digital Calibration
USB Port
Lightweight Yet Ruggedly Built
Simple 5-Button Interface

The Ludlum Model 3000 is a durable, lightweight instrument that is used with an external detector for alpha, beta, and gamma radiation survey. It features a large, easy-to-read LCD screen and audible alarms and is controlled using a simple five-button interface. The unit body is made of high-impact plastic, and splash-resistant construction allows the instrument to be used outdoors.

Three modes of operation are available – RATE, MAX, and COUNT – which can be selected by pressing the MODE button. Measurements can be collected in two sets of units (primary and secondary) for RATE and MAX modes in cps, cpm, Bq, dpm, mR/hr, or µSv/h units. The user can switch between two sets of chosen units by pressing the UNITS button. When enabled with the optional Lumic Data Logger Kit (see Options), data can be logged in any of the operational modes using the LOG button on the handle. Up to 1000 data points can be stored internally.

Instrument setup can be done either through the front-panel controls or via the Lumic Calibration Kit (see Options). The Model 3000 is shipped ready to use with batteries and calibration certificate.

Specifications

Compatible Detectors	GM, scintillation, or proportional
Display	3 digit auto-ranging LCD with large 20 mm (0.8 in.) digits. Units: (k)cps, (k)cpm, (k)Bq, (k)dpm, (µ)(m)R(/h), (µ)(m)Sv(/h). Indicators: bar graph, MAX, ALARM, USB, audio, low battery.
Display Range	0.0 cps to 99.9 kcps 0.00 cpm to 999 kcpm 0.00 Bq to 99.9 kBq 0.00 dpm to 999 kdpm 0.00 µR/h to 999 R/h 0.00 µSv/h to 999 Sv/h Operational display ranges are dependent on the detector and dead time configuration. The minimum and maximum display can be set to limit the display to the calibrated range.
Linearity	Readings within 10% of true value
Backlight	Built-in ambient light sensor automatically activates low-power LED backlight, unless internal dipswitch is set to continuous-On (will reduce battery life)
Controls	ON/OFF: Extra-long press to turn ON; Short press to acknowledge alarms; Extra-long press plus 3 seconds to turn OFF UNITS: Short press changes the units between count rate, dose/exposure, or disintegration; Extra-long press to change count time in COUNT mode AUDIO: Short press to adjust audio level MODE: Short press alternates between available modes - RATE (displays count rate), MAX (captures peak rate), and COUNT (captures rate or dose readings for a user-selectable count time from 0 to 10 minutes) LOG: Short press to log current display (requires Lumic Data Logger Kit), or initiate count in COUNT mode
Data Logging	Can store up to 1000 data points internally. Requires Lumic Data Logger Kit, see Options.
Response Time	User-selectable from 1 to 60 seconds, or auto-response rate FAST or SLOW
Alarms	Two count rate, exposure/dose, and count alarm setpoints adjustable over the display range
Overload Protection	High count rate saturation protection prevents false display of lower count rates. “OL” will appear on the display and an audio warning will be triggered.
Loss of Count Protection	After a user-defined time of no pulses from detector, typically 60 seconds, the unit will flash a zero reading, and an audio alarm will be triggered.
Overrange	If reading exceeds the predefined detector range, the instrument will flash a maximum reading and trigger an audio warning.
Dead Time Correction	Employs first and second order corrections for extended performance
High Voltage	400 to 1500 Vdc
Threshold	-4 to -100 mVdc
Audio	Approximately 4.5 kHz; Click audio greater than 65 dB at 0.6 m (2 ft); Alarm audio greater than 72 dB
Power	Four alkaline “AA” batteries
Battery Life	Approximately 750 hours of operation (as low as 100 hours with backlight configured for continuous-on), 16-hour low battery warning
Construction	High-impact plastic with water-resistant rubber seals and separate battery compartment
Temperature Range	-20 to 50 °C (-5 to 122 °F) May be certified for operation from -40 to 65 °C (-40 to 150 °F)
Environmental Rating	NEMA rating of 5 or IP rating of 53
Size (H x W x L)	16.5 x 11.4 x 21.6 cm (6.5 x 4.5 x 8.5 in.)
Weight	0.7 kg (1.6 lb) (excluding detectors and clips)
