The Ludlum Model 3000, a state-of-the-art, lightweight instrument designed to work seamlessly with an external detector for precise alpha, beta, and gamma radiation surveys. Crafted with durability in mind, this instrument boasts a sturdy, high-impact plastic body and is engineered to withstand outdoor usage with its splash-resistant construction.

Featuring an easy-to-read LCD screen and intuitive five-button interface, the Ludlum Model 3000 makes radiation measurements a breeze. Swiftly toggle between three modes – RATE, MAX, and COUNT – simply by pressing the MODE button. Choose from multiple unit sets (cps, cpm, Bq, dpm, mR/hr, or µSv/h) for RATE and MAX modes, and conveniently switch between them using the UNITS button.

With the optional Lumic Data Logger Kit (see Options), effortlessly log data in any operational mode with the LOG button on the handle. This innovative feature allows you to store up to 1000 data points internally, ensuring you never miss essential information.

Compatibility

The 3000 survey meter can be used with a wide variety of external probes.

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 Max Display can be set to limit display to calibrated range
Linearity	Within 10%
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: Press to turn ON; Tap to acknowledge alarms and silence alarm tone; Press to reset sigma audio alarm; Hold for OFF UNITS: Changes the units between count rate (cpm, cps), dose/exposure (Sv/h, R/h), or disintegration (dpm, Bq) AUDIO: Turn “click” audio ON/OFF; Turn sigma audio beep ON/OFF; Toggle volume between HI, LO, and OFF MODE: Alternates between RATE (count rate), MAX (captures peak rate), and COUNT (user-selectable preset count time from 0 to 10 minutes) LOG: Press to store meter reading (requires Lumic Data Logger Kit, see Options)
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	Count rate, Exposure/Dose, and Scaler alarm setpoints adjustable over the display range
Overload Protection	High count rate saturation protection prevents false display of lower count rates
Loss of Count Protection	After a user-settable time interval of no pulses from detector (default 60 seconds), unit will flash a zero reading and the alarm audio will be triggered
Dead Time Correction	Employs first and second order corrections for extended performance
High Voltage	400 to 1500 Vdc
Threshold	-2 to -100 mVdc
Audio	Greater than 75 dB at 0.6 (2 ft), approximately 4.5 kHz
Power	Four alkaline or four rechargeable “AA” batteries (instrument does not support in-device charging)
