  • Description

    The Ludlum Model 19 is a highly sensitive gamma radiation MicroR survey meter employing an internally housed, 1.0 in. diameter by 1.0 in. thick (2.5 x 2.5 cm) NaI detector.

    Add a Counts.Pro for to digitize and record your Model 19 surveys and turn your meter into a digital scaler/ratemeter/cloud connected GPS datalogger!  Take your meter to the next level with Counts.Pro

    The measuring range is 0-5000 µR/hr (0-50 µSv/h). The cast aluminum instrument housing with its separate battery compartment and accompanying metal handle offer an industrial robustness and quality that promote long lasting protection and instrument life. The front-panel controls include a rotary switch for selecting the five-decade range and instrument shut-off, an audio on/off switch, a fast/slow response switch, and pushbuttons for activating the meter lamp, high-voltage display, battery test, and count reset. The Model 19 is a complete turn-key system and includes two "D" cell batteries.
