The Ludlum Model 3000 is a versatile, lightweight, ergonomically-designed instrument used with an external detector for alpha, beta, or gamma radiation survey. Three modes of operation – RATE, MAX, and COUNT – are available for the user. 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 simply pressing the Units button.
The standard handle includes the LOG pushbutton that allows the instrument to log up to 1000 data points when activated with the optional Lumic Datalogging Kit. See the Options tab for more information.
An internal switch is used to enable or disable the front-panel setup feature to protect desired settings from inadvertent modification. Setup is also available via software available from Ludlum Measurements. User-adjustable settings include calibration constant, dead time correction, efficiency, high voltage, pulse threshold, response time (fast or slow), count time, operational modes, HV current overload level, operational mode (Rate, Max, or Count), and minimum and maximum display levels. The user may also set Primary and Secondary units, unit alarm levels, count units, count alarm levels, and zero pulse protection time limit.
This instrument features a large, easily-readable LCD (liquid crystal display), an audio warning tone, and easy, intuitive, user-friendly design. Splash-resistant construction allows the Model 3000 to be used outdoors. The instrument body is made of lightweight, durable, high-impact plastic. The Model 3000 is shipped ready to use with batteries and calibration certificate.
The Model 3000 Series of Digital Survey Meter is available with several options that enable the user to further exploit the many features of this instrument. Several of these options are listed on the Options tab and on the Options Data Sheet found on the Documents tab.

Max Display can be set to limit display to calibrated range |
| 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/ACK |
- Press to turn ON
- Tap to acknowledge alarms and silence alarm tone
- Press to reset Sigma Audio alarm
- Hold for OFF
|
| Mode |
Alternates between:
- NORMAL (count rate)
- MAX (captures peak rate)
- COUNT (user-selectable preset count time from 0 to 10 min)
Number of modes can be reduced in setup. |
| Audio |
- Turn “click” audio On/Off
- Turn Sigma Audio beep On/Off
|
| Units |
Changes the units between:
- Count rate (cpm, cps)
- Dose/exposure (µSv/h, mR/h)
- Disintegration (dpm, Bq)
|
| Data Logging Handle |
Instrument is supplied with built-in push button data logging handle.
(NOTE: Datalogging Software [P/N 4498-1019] is required to use this feature) |
| 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 |
High count rate saturation protection prevents false display of lower count rates |
| Zero 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 |
