Digital Hand Held Spectrometer & Dose Rate Meter with Nuclide Identification

The world's smallest spectrometer, dose rate meter and nuclide finder.

Features

Allows to 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 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 137Cs reference source (¡Ö 500 Bq/15 nCi) is used for online stabilisation and in-situ calibration without user interaction.

This special feature allows operational temperatures between -15°C and +55°C and large temperature gradients.

Connected to a computer via infrared, Connected to a desktop or notebook PC, the unit provides qualitative and quantitative in-situ analysis with optional gam TMCA-N software.

Up to 70 spectra of 1024 channels can be stored in the unit and directly transferred to any PC for further and advanced analysis.

Standard winTMCA software is part of delivery.
