fire IdentiFINDER Digital Hand Held Spectrometer & The world s smallest spectrometer and dose rate meter designed for portable applications. safety security identifinder - CH (yellow) CZT and neutron detector version identifinder - N (red) Standard version defence identifinder - NH (blue) Standard version with neutron detector Features This instrument will distinguish man-made and natural isotopes; it combines high sensitivity with a wide dose rate range. It performs gamma spectrometry and nuclide identification. It is a complete digital gamma spectroscopy and dose rate system, it integrates multi-channel analyser, amplifier, high voltage power supply, and memory with an integral scintillation detector; it is well suited for remote applications, advanced warning systems, hazardous environments and nuclear inventory monitoring. It can be used with standard detector Ø 1_ x 2_ NaI(Tl), or the optional available BGO or CdWo detector as well as CdZnTe. A built-in 137 Cs reference source (<500 Bq/15 nci) is used for online stabilisation and insitu calibration without user interaction. This special feature allows operational temperatures between 15 C and +55 C and large temperature gradients. It can be connected to a computer via infrared, or connected to a desktop or notebook PC, the unit provides qualitative and quantitative in-situ analysis with optional wintmcapro software.

NUCLIDE The operator can select from 6 sub-libraries (Nuclear, Industrial, Medical, Customs, CTBTO, and User). All sub-libraries except CTBTO can be edited by adding or deleting specific nuclides from the list. Ten (10) reference spectra can be measured by the user and added to the predefined library spectra. Identification is done by a template matching correlation procedure. Page 2 of 5
