The Model 25 Series are personal radiation monitors designed to warn users any time they are in a potentially harmful radiation environment.

The Model 3 is a general purpose, analog ratemeter that can be used with a variety of GM and scintillation detectors for radiation surveying.

The Model 14C survey meter supports operating two separate radiation detectors, an internal GM detector and an external GM or scintillation detector.

The Model 14C-RK includes the basic radiation measurement tools required to rapidly react to a radiological emergency. It includes two detectors, a Model 44-2 gamma scintillation detector and a Model 44-9 alpha-beta-gamma GM detector, matched with the Model 14C survey meter.

The Models 9-4 and 9-4RF are rugged air ionization chamber meters for measuring beta-gamma dose rates. The Model 9-4RF has improved components and shielding to pass RF susceptibility tests at military levels up to 18 GHz.

Handheld microR (µR) survey meters are used in the metal recycling industry to pinpoint contamination sources in vehicle loads after an initial radiation alarm has been triggered by a Radiation Portal Monitor (RPM). This video provides a brief overview of the Ludlum Models 19, 3019, 192, 193-6, and 30-6 and demonstrates how microR meters can be used.

This video demonstrates how the Model 19 and Model 30-6 can be used to pinpoint the source of radioactive contamination in a truck load.

The Model 19 is a highly sensitive gamma microR meter with an internal 2.5 x 2.5 cm (1.0 x 1.0 in.) NaI detector.

The Model 19A is a highly sensitive gamma microR meter with an internal 2.5 x 2.5 cm (1.0 x 1.0 in.) NaI detector. It has an alarm and a logarithmic meter scale.

The Model 193-6 is a highly sensitive gamma microR survey meter with extended reach capability. It has a very sensitive 15.2 x 2.5 cm (6 x 1 in.) plastic scintillator detector mounted at the end of a 1.2 m (4 ft) long pole to facilitate reaching elevated areas.
