The Weston cell, is a wet-chemical cell that produces a highly stable voltage suitable as a laboratory standard for calibration of voltmeters. Invented by Edward Weston in 1893, it was adopted as the International Standard for EMF between 1911 and 1990.[1] This is a type of standard cell, which is a battery that produces a precisely known voltage in laboratory conditions at 20 degrees centigrade.[2]Brass cylinder with 4 connections at top. Two marked 'A' and the other two marked 'B'. Black plastic nob in the centre top.

Used in physics/optics laboratory at Mt Helen, most probably transferred from SMB to Mt Helen c1870 as SMB start date but could be much earlier A vertical arrangement of lenses, mirrors and polarisers mounted on a brass stand 50cm high with a heavy metal claw foot base. Circular calibrated 360 degrees platform with small brass clips holding a glass lens in position. Parts appear to be original, though the object appears to be missing a eye piece, a mirror to reflect the light, and a viewing platform.CS - 77optics, lenses, mirrors, smb, rocks, microscope, polarisers, scientific instruments
