Ludlum Measurements, Inc! The portable Model 702i isotopic measurement system was developed to give end users such as first responders a simple tool to quickly locate any abnormal levels of radioactivity, and to accurately identify the isotopes present.

The instrument houses an internal 5.1 x 3.8 cm (2 x 1.5 in.) NaI detector. Its signal is gain stabilized and automatically calibrates itself via an embedded 40K source. The Model 702i additionally offers several advanced features for well-trained experts seeking to perform more detailed analysis either in the field or in a laboratory.

Spectra can be captured to a removable CompactFlash disk or sent to a PC via an Ethernet connection. Quantum™ PC software to analyze the spectra more thoroughly is included along with a NiMH battery charger.
