Now available as the NGT-075-B2!
NGT-075-B
Gamma Tools (.075” OD)
The NGT-075-B gamma tool has an outside diameter of only 0.75” and is ideally suited for mounting within drill-collar walls for azimuthal gamma or bulk gamma applications. Encapsulated and cushioned within pre-molded high-temperature silicone pads, the printed circuit boards are protected from extreme shock and vibration.
