GS-1100-PRO "Now standard with two wire detector option"
When you have a great product which works as well as the GS-1100A it's not easy to make small improvements, so we decided to start from scratch. The GS-PRO model has been redesigned from the ground up, virtually nothing is the same as the 1100A.
In the outset we wanted a more stable Gamma Spectacular, which would hold it's voltage, even through temperature changes, also we wanted the ability to regulate voltage smoothly over a range, rather than in increments of 50V. These objectives were achieved through the use of a precision voltage reference source which stabilizes the output voltage via a feedback circuit, and it performs excellently, with virtually no voltage drift, even ruring the startup phase.
We did not stop there, we also added a digital voltage panel meter, completely redesigned the pre-amplifier and added an optional signal input for detectors with two cables.
There is a small switch accessible under the unit which allows the user to switch from integral coupling to external coupling (single or two wire detectoprs).
What you can expect from this new unit, is more control and sharper spectra right from the start.

Gamma spectacular outputs an audio signal proportional to the input pulse energy, and is designed to work with sound card spectroscopy software, utilizing the analog to digital capabilities of modern computers.
This unit does not come with a radiation detector. For basic radiation activity measurements, it will work with most GM tubes or pancake detectors, and for Gamma spectroscopy it will work best with NaI scintillation detectors coupled for positive voltage. Please feel free to send us the make and model number of your radiation detector, to confirm suitability.
Any computer with a sound card and mic/line in audio jack port will work. The recommended software is for PC, but it will work perfectly on Mac OS-X with Crossover by CodeWeavers
There are several great programs available for soundcard spectrometry, and most of them are FREE, please see our software download section for the program that suits your need here.
