content: A reproduction of William Thomson's absolute electrometer, based upon his description in the report of the British Association for the Advancement of Science (B.A.A.S.) for 1867, plate 6, Fig. 11. A wooden base with a wooden stand at one end and a brass tripod at the other. The wooden stand is two columns connected by a wire that serves as a pivot for a metal fork. A brass weight can be set on the end of the fork. The fork itself engages a ring on top of an adjustable weight mechanism mounted in the tripod. A glass lens with a guide bar is on the tripod opposite the stand, and an adjustment screw is set below the lens at the bottom. Nameplate reads: "L.C. Eichner / Instruments / Clifton, NJ". There are two vertical scales (ivory?) set on the adjustable mechanism.
