GR1 CZT gamma-ray spectrometer

A family of small and light CZT-based gamma-ray spectrometer

Put a radiation detector places you never thought possible

The Kromek GR 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.

Can be used across all radiation detection needs either used straight out of the box or built into your own devices. They can be mounted side by side in an array to give you coverage of a large area.

GR CZT-based gamma-ray detector models

Pick the resolution and output you need

The GR family comes in a number of models. The Plus (+) model feature higher resolution than the base model. The A-model feature different outputs for some who want to access more of the raw data coming out of the detector. The GR05 model has a smaller CZT detector designed to operate in areas of high-flux (high-count).

Powerful software included

Both the GR1-A and the GR1-A Plus include MultiSpect Analysis our powerful spectroscopy software

GR1 on drones

The small size and power requirements of the GR devices make them perfect for drones and other in-field uses. ImiTec Ltd develops and manufactures novel methods for detecting, characterising and mapping radiation, and use our GR1 devices on their drones.
