Model 703e Isotope Identifier with External Detector

The Model 703e Integrated Spectroscopy with External Detector is equipped with a larger 7.6 x 7.6 cm (3 x 3 in.) detector. It was developed to give end users, such as first responders, a simple tool to quickly locate any abnormal levels of radioactivity and accurately identify the isotopes present. It additionally offers several advanced features for well-trained experts seeking to perform more detailed analysis either in the field or in a laboratory. Connection to a PC is available via a built-in Ethernet connection where stored or real-time collected data can be processed by optional isotopic analysis programs.

The 700-Series employs time-slicing and patented QCC technology that delivers improved energy resolution, real-time background subtraction, and the highest degrees of sensitivity. These units have a trace amount of ⁴⁰K embedded to provide gain stabilization and self-calibration. The use of a Model 4-40 eliminates the need of a radioactive source to accomplish the same result. All captured spectra data are stored to a removable compact flash card in ANSI N42.42 standard format.

This convenient storage medium facilitates quick removal for review elsewhere as well as allowing virtually an unlimited number of spectra to be collected while in the field. These instruments were the very first ones designed to meet ANSI N42.34 Performance Criteria for Handheld Instruments for the Detection and Identification of Radionuclides. The design was also optimized for portability, user-friendliness, and rugged use out in the field.

An ergonomic shape and excellent balance allow them to be operated with a single (gloved) hand with easy thumb access to a set of very large tactile type control buttons. The 8.9 cm (3.5 in.) color LCD is a transflective type, which brightens with use in bright sunlight conditions that typically render other types of LCDs useless. The use of color on the different displays is intelligently applied signifying the appropriate activity levels for capturing spectra, labeling isotope categories, and presenting alarms. Audible feedback and voice alerts further enhance the user interface. This instrument is powered with rechargeable NiMH batteries delivering up to eight hours of portable use.
