DETECTIVE Basic features of the series of products:

Detective series of products are highly integrated portable high-purity germaniumThe spectrometer and nuclide discriminator combine the achievements of today's high-purity germanium technology in electric refrigeration, electronics and software, and combine it with advancedCommunication technology, with a considerable level of intelligence, is today’s high-purity germaniumThe embodiment of technology. since 2004 Since its launch in 2016, the product has

Yes 1,500 Multiple sets of homeland security and emergency surveillance systems operating in countries around the worldtesting, environmental protection, nuclear power, inspection and quarantine and medical and health departments.

² Integrated using high-purity germanium,GM Guan HeHe-3 neutron(optional）Detectors to meet the requirements of anti-terrorism and nuclear emergencies quickly and accuratelyQualitative and quantitative requirements.

² Micro Stirling compressor refrigeration,Cooling can be initiated at any detector crystal temperature.

² press ANSI N42.34 Standard, which can comprehensively and accurately identify all nuclides of the measurement object within a few seconds to tens of seconds.The system software automatically generates reports based on industrial, medical, natural and special nuclear materials.

² The operation is very simple and convenient. The system has a considerable level of intelligence. For example, for the identified special nuclear materials（Special Nuclear Material, SNM）, the system will automatically guide further measurements.

² integrated digitalizationMCA, the performance index is equivalent to ORTEC DigiDART。

² Multiple power supply modes: internal battery, external battery pack and charger for external power supply（communicate/DC/car power supply）。

² Today's trendy touchPDA, built-inGPS，RAM memory card, Wi-fi Wireless communication.

² The detector orientation can be arranged arbitrarily without affecting performance and life.

DETECTIVE-200 Unique features:

² Larger crystals:Φ85mm ´ L30mm, the relative efficiency is greater than 50%, especially in the medium and low energy range and has excellent actual detection efficiency for large-area objects.

² Faster response speed under nuclide screening function.

² A considerable degree of waterproof, dustproof and dust-proof design to achieveIP67 standard. Able to adapt to work under harsh environmental conditions.

² Have List Mode mode, combined with professional software, can be used for source search, container scanning and other mobile measurements.
