GT-32 is a field gamma-ray spectrometer for rapid determination of potassium, uranium and thorium concentrations with increased sensitivity. It can be used for geology applications in field surveys for raw material sources. Proven performance in harsh environment applications. Survey data is stored in the memory, including the GPS coordinates. This instrument is calibrated to measure concentrations in soils in open space.

2 modes

Two basic working modes: Survey, for terrain scanning, and Assay, for determining K, U and Th concentrations. The Survey mode has an added ON FLY ASSAY function running simultaneously. This function calculates estimates of K, U and Th concentrations of the surveyed territory and in time-equidistant sections.

Energy calibration of the analyzer is carried out continuously throughout the operating time, and only natural background sources are used for the set-up. Monitoring and analysis results are displayed on a graphic display in a well-arranged manner. All acquired data is stored in the unit’s memory and can be exported to other devices via USB or Bluetooth.

Audible indication of changes in the frequency of recorded gamma particles is provided by a speaker located behind the rear cover of the unit, or via USB headphones.
