GR1 CZT gamma-ray detector spectrometer

A family of small and light CZT-based gamma-ray detector spectrometers

Gamma ray detector spectrometer for civil nuclear and radiation security use.

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 gamma radiation detection needs either straight out of the box or built into your own devices. The GR gamma ray detectors can be mounted side by side in an array to give you coverage of a large area.

The GR1 range of gamma-ray detector spectrometers is just one of our radiation detections products you can see the complete radiation detection product range here.

Gamma-ray detector spectrometer models

Pick the gamma-ray detector resolution and output you need

The GR gamma-ray detector spectrometer family comes in a number of models.
The GR1 Plus (+) Gamma-ray detector spectrometer model feature a higher resolution than the base gamma-ray model.
The GR1 A-model feature different outputs for some who want to access more of the raw data coming out of the gamma-ray detector.
The GR05 model has a smaller CZT detector designed to operate in areas of high-flux (high-count).
