title: GR1 Webinar Recording
description: The Kromek GR1 family is a range of CZT-based high-performance gamma-ray spectrometers. They are 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. The unit is powered entirely from the USB bus, so no external power supply is needed.
