Sort By:

CZT-based, Room Temperature, High-resolution Radiation Detector

GR1® - Gamma Ray Spectrometer

The Kromek GR1® is a high-performance gamma ray spectrometer utilizing a 1-cm3 CZT detector. It is completely self-contained, with built-in preamplifier, shaping amplifier, baseline restorer, pulse height digitizer, and HV supply. The digitized pulse heights of detected gamma-ray signals are sent to a PC via the USB.

Advanced GR1, GR1-A®

The Advanced GR1® (GR1-A®) is a USB-powered gamma spectrometer employing the same 1cm3 CZT detector and electronics used in the GR1 but has additional auxiliary input/outputs that greatly increase operational flexibility.
