Ludlum 133-6 and 44-2 Radiation Simulation Probes

Realistic, Safe, and Comprehensive Radiation Detection Training

LUDLUM 133-6 & 44-2 METER

Radiation Simulator Probes

The Ludlum 133-6-SIM and 44-2-SIM are advanced radiation simulator probes designed to replicate the operational features of the Ludlum 133-6 Gamma detector and the 44-2 scintillation detector.

These simulators provide unmatched realism and usability, enabling trainees to master radiation search, survey, and localisation skills without the need for real radioactive sources. Compatible with Ludlum meters, these probes offer a versatile and cost-effective solution for comprehensive radiation safety training.

Key Features

  • Expertly Designed: Identical user interface and operational characteristics to the real 133-6 and 44-2 detectors.

  • Incredible Realism: Response speeds closely mimic real detectors, supporting realistic source search and localisation exercises.

  • Effortless Integration and Versatility: Compatible with any Ludlum meter supporting 133-6 or 44-2 probes. o Fully compatible with PlumeSIM and other Argon simulation systems.

  • Simulated Science: Inverse square law (1/r2) response within real detector tolerance.

High Impact Radiation Training

Response speed and characteristics are very similar to the real detector permitting realistic source search/find training to be provided.

Simulated delivered sensitivity enables the 44-2 Simulator probe to detect the RADSIM GS4 simulation Gamma/Neutron source at a free space distance of typically 200 feet (60 metres) distance line of sight. Our powerful Radsim source App enables you to set a wide range of simulated source activity

Cost Effective, Consistent and Repeatable 

Powerful proprietary signal processing ensures simulated readings are repeatable each time students revisit the same scenario location and also ensure the readings observed on different simulators are within the accepted tolerances of actual detectors; all contributing to the provision of high-quality training and easy exercise set up.

No preventative maintenance, calibration or consumables (except batteries) are required ensuring whole life cost of ownership is minimal.

The Ludlum 133-6-SIM and 44-2-SIM probes provide the ideal solution for safe, realistic, and impactful radiation training.
