NGT-CSX-B Gamma Tool

NGT-CSX-B

1.05″ OD Gamma Tools

The NGT-CSX-B gamma tool is a shorter version of the original NGT-CS tool.  With a diameter of only 1.05”, it is ideal for either probe based systems or collar mounted assemblies.  While the crystal is only 0.625” in diameter, its 6.0” length produces a sensitivity very similar to the standard, larger diameter NGT-T.

Magnetic materials have been minimized to prevent interference with nearby magnetometers.
