AnaLog Services, Inc. is often asked to upgrade cement bond logging tools and surface equipment.  Over the years, we have developed a series of printed circuit boards (PCBs) using some of the best elements of the many designs out there.  The two solid state bond amplifiers listed below can be used to upgrade old SIE Nuvistor amplifier tools, or can be used in other rebuilds or new tools.  The Universal Bond Kill PCB will work with virtually every gamma-ray or gamma-ray / neutron tool ever made (it has positive and negative pulse output as well as a grounding transistor switched output).  All PCBs listed below use readily obtainable components, which parts will continue to be available for many years to come.

Contact us if you have equipment needing an upgrade, or if you wish to obtain PCBs for your own project.  Click on the links in the "PCB" column for photos and additional data on the boards.
