Ludlum’s Model 3-98 is uniquely configured to optimize measurements for 125I and any alpha beta gamma contamination. Buckhorn offers this meter with a check source and probe for calibration and ease of use.

The dual detector design allows the user to select the detector for the task at hand. The internally-housed GM pancake detector can be used to read gamma. This detector’s face can be exposed via a slide located along the bottom of the instrument, thus making it sensitive to alpha and beta as well. The external NaI detector, Ludlum Model 44-3, is optimized for low-energy gamma from 125I. The ratemeter is Ludlum’s venerable Model 3 series, which employs a robust aluminum cast instrument housing with a separate battery. The front-panel controls include a rotary switch for selecting the 4-decade range, instrument shut-off and battery test, audio on/off switch, fast/slow response switch, count reset button, and internal/external detector switch.
