An aneroid barometer is an instrument used for measuring air pressure as a method that does not involve liquid. Invented in 1844 by French scientist Lucien Vidi, the aneroid barometer uses a small, flexible metal box called an aneroid cell (capsule), which is made from an alloy of beryllium and copper. The evacuated capsule (or usually several capsules, stacked to add up their movements) is prevented from collapsing by a strong spring. Small changes in external air pressure cause the cell to expand or contract. This expansion and contraction drives mechanical levers such that the tiny movements of the capsule are amplified and displayed on the face of the aneroid barometer. Many models include a manually set needle which is used to mark the current measurement so a change can be seen. This type of barometer is common in homes and in recreational boats. It is also used in meteorology, mostly in barographs and as a pressure instrument in radiosondes.5 inch Aneroid barometer on wooden basebarometer, aneroid

Gunter's chain (also known as Gunter’s measurement) is a distance measuring device used for surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). It enabled plots of land to be accurately surveyed and plotted, for legal and commercial purposes. The provenance of this particular Gunter Chain is unknown but it is believed to be used either by the City of Bendigo / Sandhurst or the Lands Department locally when measuring and laying out plots and streets locally. A 66-foot (20.1 m) chain divided into 100 links, marked off into groups of 10 by brass rings or tags. Each link is 7.92 inches (201 mm) long. A quarter chain, or 25 links, measures 16 feet 6 inches (5.03 m) also called a a rod (or pole) measure. Ten chains measure a furlong and 80 chains measure a statute mile. city of greater bendigo surveying

A pennyweight was a unit of mass that was equal in weight to 20 grains, one twentieth of an ounce and one 240th of a Troy pound. The abbreviation for a pennyweight is ‘dwt’ (denarius weight). These measures and weights were typically used for weighing gold and other precious metals.

Victoria became a separate colony of the United Kingdom on 1 July 1851; however it took until 1864 for a workable system of weights and measures administration to be introduced. Standard of weights and measures were obtained and issued to local authorities to administer in their local areas. These standards were numbered, as were the Crown stamps used by inspectors to indicate that trade weights and measures had been checked and found to be legal to use in the day-to-day businesses of local traders. By the 1870's each local council had a set of standards that were used to test the scales, weights and measures of local merchants and businesses.Standard 28lb brass measure.

An original Kerr-Grant Microbalance, modified by E.J.Hartung This balance was invented in the chemistry department by Bertram Dillon Steele, later first Professor of Chemistry at the University of Queensland 1910-1930, in collaboration with Professor Kerr Grant, Physics. The design was widely used by other chemists, including Masson's mentor, Professor Ramsay, working in London on newly discovered rare gases (especially Radon), and Professor Hartung in Melbourne, investigating the chemistry of the decomposition of silver salts in photographic processes. The principle of the microbalance was to measure the change in density of a gas by the shift in the balancing beam due to a change in pressure of the gas in the balance case. The quartz balancing beam was made by Bertram Steele who was particularly skilled in glassblowing. A quartz beam is the beam of the Aston microbalance based on the Steele/Grant instrument, and described by F.W. Aston, the inventor of the mass spectrometer. The bulb at one end of the beam contained a fixed amount of air, so that a change in the pressure of gas in the balance case changed the buoyancy of the beam, yielding a displacement in the beam which could be measured. By this means, differences in weight of about 10 nanogram could be measured, in amounts of up to 0.1 gram. Such differences are significant the increase in weight of a metal sample due to surface oxidation (Steele's interest) in the weight loss due to radioactive decay of Radium (Ramsay's work), and in the estimates of density change due to the isotopic distribution of Neon (Aston). Ernst Johannes Hartung was a chemist and astronomer. Educated at the University of Melbourne (BSc 1913, DSc 1919), he became lecturer in 1919, associate professor in 1924, and succeeded Rivett as chair of chemistry in 1928, remaining in this position until 1953. Hartung?s lecturing style surged with enthusiasm and he employed the use of screen projections to demonstrate chemical phenomena to large undergraduate classes. In 1935 he recorded Brownian movement in colloidal solutions on 35 mm cinefilm, which was later copied onto 16 mm film for the Eastman Kodak Co. World Science Library. This can be viewed in the Chemistry laboratory. He researched the photo decomposition of silver halides, and was awarded the David Syme Prize in 1926. He devoted time to the design and construction of a large, new chemistry building for the School of Chemistry (built 1938?1939). During World War II he was approached by Professor Thomas Laby, chairman of the Optical Munitions Panel, to chair the advisory committee on optical materials, to produce high quality optical glass in Australia. This was successful, with large-scale production achieved within ten months at a reasonable cost. Hartung served three terms as general President of the (Royal) Australian Chemical Institute, was an ex-officio councillor of the Council for Scientific and Industrial Research, and a Trustee of the Museum of Applied Science (now part of Museum Victoria).An original Kerr-Grant Microbalance, modified by E.J.

This device was used to measure surface wind speed and direction. This anemometer was located on a concrete pad outside room 2.15 on a steel pole. The pole was considered unsafe and the anemometer was relocated to it's current position. When lowering the pole it fell over and was badly damaged. The Bureau of Meteorology donated it to the museum. It was then repaired and restored. The central pole on which it is mounted is galvanised iron pipe painted black. The anemometer, a portable device that manually measures wind speed, was a necessary instrument once common to all weather stations. The arms are attached to a vertical rod and as the wind blows, the cups rotate, making the rod spin. The stronger the wind blows, the faster the rod spins. The anemometer counts the number of rotations, or turns, which is used to calculate wind speed, surface wind and direction. They were designed to be durable to withstand the corrosive environment and strong winds expected at coastal sites such as those at Gabo Island. Anemometers existed in the nineteenth century and their design was improved by various experts including John Robinson in 1846, John Patterson in 1926, Brevoort and Joiner in 1935 and Derek Watson in 1991 who added wind direction measurement to its functions. This example was made for the Bureau of Meteorology by the Melbourne instrument company, Synchrotac, which became registered and incorporated on 26 July 1966. It is now displayed inside the building. A good example of its kind, the anemometer has first level contributory significance for its historic value and provenance to the lightstation.Anemometer and tripod stand.

Used on Gabo Island to measure maximun gust over previous 3 hours or between weather observations. Information on the back of the device implies that it was battery powered and indicates that it was used in conjunction with a Synchrotac brand anemometer. Its particular function was to measure maximum wind speed over three hours between weather observations. Like the other weather recording instruments in the collection, it became redundant to the Bureau of Meteorology’s needs. It is a good example of its kind and has first level contributory significance for its historic value and provenance to the lightstation.Black metal box with grey metal front.
