Product Description

Laboratory high purity germanium gamma spectrometer

Product introduction

The laboratory high purity germanium gamma spectrometer independently developed by our company is a set of domestic high purity germanium spectrometer products, which is mainly composed of P-type HPGE detector with relative efficiency of 50%, low background lead chamber, digital multi-channel, and supporting GammaSense spectrum analysis software.

The digital multichannel integrates the signal polarity adjustment unit, the fast analog-to-digital conversion (ADC) unit, the autorotor/zero cancellation unit, the digital baseline recovery unit, the digital trapezoidal forming unit, and the digital anti-echo/anti-universe interface unit for advanced applications.

GammaSense energy spectrum analysis software is a complete set of spectrum analysis software, with internal functions of energy scale, efficiency scale and double peak analysis. The operation interface is all in Chinese, which can give the activity of radioactive samples in real time. The results can be presented in the form of a report, which can be printed by the user directly through the printer.
