700 Series

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. The signal is gain stabilized, and the instrument automatically calibrates itself via an embedded 40K source. The 711i contains a LaBr detector and identifies mixed isotopes
