This pH meter was made in 1946 by Cambridge Scientific Instrument Co. Ltd. in London. The company was founded in 1881 and the owner eventually became Horace Darwin, the youngest son of the famous scientist Charles Darwin. It is a portable version that can be used on-site in many different situations. A similar instrument was used by the Chemistry Department of what is now the University of Cambridge. The science of pH measurement began in the 1910s and was further developed in 1926. The pH meter is an electronic scientific instrument used to determine the pH measurements of a solution accurately; the amount of acid and alkaline in it This measurement can have many other applications helping to maintain the appropriate balance for a particular result. For example, it can measure the pH of pharmaceutical medications, soil, swimming pool water and hair shampoos. This Cambridge portable electronic pH instrument was made in 1946 by a company specialising in scientific instruments. It is an early example of much smaller devices used today in many different fields including medicine, and the preservation and conservation of shipwreck artefacts. Flagstaff Hill Maritime Museum and Village's Curator uses a pH meter today in the conservation process of a historic cannon that was recovered from the 1839 wreck of the vessel 'Children'.Scientific instrument, electric Cambridge Portable pH Meter in a polished wooden box with compartments, fold-out doors, and leather carry handle.

This meter belonged to the State Electricity Commission of Victoria. This meter measured the power used by all the houses in Mount Beauty and provided an inked one month period chart. This information was used to quantify and pay for the power consumption to the Transmission and Generating Department from the Distribution Department which then went on to bill local consumers.The State Electricity Commission of Victoria constructed the Kiewa Hydro Electric Scheme from the late 1930's to the 1960's. The construction towns of Bogong and Mt Beauty used electricity which was measured by this meter resulting in billing customers for the power they used.Black box with black painted wooden frame top and bottom screwed on holding clear glass at the front so that the instruments can be seen. A metal cylinder is at the bottom of the instruments with a connecting rod to the 7 digit meter in the middle of the instrument panel.
