Gammacom dosimeters

["Boomologist" <boomologist@GotHotRocks.com>]

Hi,

I am attempting to locate schematics for the Gammacom 4200 dosimeter made by R.A. Stephan Co. in England. They are not in business and were bought out by Thermo. Thermo only has operation manuals for these.

We also need the manual for the programmer unit for these dosimeters.

                       Thanks in advance,
