The Model 3001-3RK (formerly called Model 3001-3RK2) consists of several dependable, high-quality detectors matched with the versatile Model 3001 survey meter. The devices are packaged in a rugged transport and storage case with the required batteries, cable, and calibration certificate for a radiation emergency response kit.
The primary instrument, the Model 3001, is an ergonomically-designed instrument with four selectable detector buttons, enabling the user to quickly exchange detectors in the field. Alpha, beta, and gamma surveys may be conducted in two sets of units. The desired unit is chosen by pressing the Units button. A color-coded button selects the desired detector. An internal switch is used to enable or disable the front-panel setup feature to protect desired settings from inadvertent modification. Three modes of operation - RATE, MAX, and COUNT - are available. A large back-lit LCD screen, intuitive interface, warning alarm, and durable, splash-proof construction mean the Model 3001 will be the instrument of choice for your kit.
Three detectors, the popular Model 44-9 alpha-beta-gamma detector, Model 133-6 gamma detector, and the Model 44-2 high-energy gamma detector, accompany the Model 3001.
The transport and storage case includes dense pick-and-pluck foam, watertight capability, and hasps with padlock holes for additional security. A manual pressure relief valve is used in consideration of potential transport by aircraft.
Ludlum provides a 1 µCi ( 137 Cs) check source, check source holder, cable, and calibration certificate making this kit ready-to-go.
Ludlum offers several versions of pre-packaged response kits suitable for a wide variety of applications. If you desire more or different detectors, or other changes to our standard kits, please contact us regarding a customized kit.

Backlight Built-in ambient light sensor automatically activates LED backlight, unless internal dipswitch is set to continuous-On (will reduce battery life)
ON/ACK: 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 (µSv/h, mR/h), or disintegration (dpm, Bq)
DETECTOR: Selects active detector
MODE: Alternates between RATE (count rate), MAX (captures peak rate), and COUNT (user-selectable preset count time from 0 to 10 minutes). Number of modes can be reduced in setup.
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 s, 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 (default 60 seconds) of no pulses from detector, unit will flash a zero reading and the alarm audio will be triggered
