Designed to be used with the ICS-4000e Radionuclide Identifier, the XP probe contains a 10x10x1 CdTe detector and a charge sensitive preamplifier mounted in a 1" diameter x 6" long housing. The XP probe can be used with up to 500' of cable providing a high resolution spectrometer for a variety of measurements that would otherwise be impossible. The ICS-4000e Radioisotope Identifier provides a 4000-channel multichannel analyzer and LCD to accurately display labquality spectra of gamma ray photons with energies from 10keV to 2MeV.
