About WB Johnson

home / About WB Johnson

WB Johnson Instruments, formerly WM B. Johnson, was founded in 1955. Mr. William Johnson, a health physicist who attended Purdue University and worked on the Manhattan Project.

In the beginning, our products were mainly specialty instruments and detectors built under contract for the U.S. Navy, including quartz fiber pocket dosimeters and hand held survey meters. In the 1970’s WM. B Johnson developed a significant market for very high range telescoping survey meters (utilized around nuclear reactors) and quartz fiber pocket dosimeters, and thereby obtaining 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 much larger different capability and a vision of what WM. B Johnson had the capability to be. This new vision, 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. Within a few years, the new owners had incorporated the latest field proven technology in Johnson’s new line of instrumentation and detectors.

Since 1955, the WM B. Johnson brand has become one of the most recognized names in radiation detection instrumentation, being known previously as the “Baby Blue” meters. The organization was purchased in 2011 and the name was changed to WB Johnson Instruments. WB Johnson is continuing to honor our reputation as a quality instrument manufacturer while working 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 dedicatioon to our customers and thier needs is and always will be our primary objective. Contact us today to see how the New WB Johnson Instruments are the only thing bettter than the original.
