This enabled us to obtain the rights to manufacturer a high quality, flexible alpha scintillator, used extensively by government and private laboratories to measure radon and special nuclear materials.

In 1988, due to the death of William Johnson, the company was sold to a new managment group. The new owners’ brought a fresh perspective and efficiency beyond what WM B. Johnson had envisioned. This new outlook, combined with their vast experience in designing and manufacturing electronic and nuclear monitoring instrumentation, led Johnson down the path to building a brand synonamous with quality radiation products. It wasn’t long before the new owners had incorporated the latest field proven technology in Johnson’s new line of instrumentation and detectors.

Known previously as the “Baby Blue” meters, the WM B. Johnson brand has become one of the most recognized names in radiation detection instrumentation. After our acquisition and name change to WB Johnson Instruments in 2001, our honor and reputation as a quality instrument manufacturer has never waived. WB Johnson Instruments continues to improve and expand our current product line with a full spectrum of radiation detection and measurement instruments built with the end users needs as our top priority. Our dedication to our customers and their needs, is and will always be, our primary objective.
