Product Details

NGT-CN High Sensitivity Non-Directional Gamma Tool (1.36” OD)

The NGT-CN High Sensitivity Non-Focused Gamma Tool is similar to the NGT-T model but has 40% higher sensitivity due to its longer scintillator crystal. The NGT-CN is interchangeable with the standard NGT-T gamma tool. It is the same overall length and diameter as the NGT-T but is used in high sensitivity non-focused gamma applications.

To protect your gamma investment and ensure the best performance use CBG original SNB Snubbers-Shock & Vibration Isolators.
