Stevenson screens were first introduced in Australia in the 1880s and were widely installed by 1910. The screens have been used to shelter and protect thermometers and other meteorological instruments from rain and direct heat while the holes and double-louvre walls allowed air to flow around them. Sometimes other meteorological instruments were included in the weather stations, so there were different Stevenson Screen sizes. This authentic, original Stevenson screen was previously owned by the Australian Bureau of Meteorology and was used for many years for weather readings at the Cape Otway Light Station in southwest Victoria. The Lighthouse Keepers recorded the readings for minimum and maximum temperatures at 9 a.m. every day from January 1865 until April 1994. The equipment was sheltered in a Stevenson Screen from 1902 until April 15 1994, when the mercury thermometer was replaced by a platinum resistance probe within an Automatic Weather Station (AWS). This Stevenson screen is one of the two screens that then became redundant. The other Stevenson screen was kept to display to visitors. Lightkeepers were no longer required at the Cape Otway Light station either, due to the automated system. The meteorological instruments donated with the screen were used for measuring temperature and humidity. They are mounted on a metal bracket that fits across the screw holes on the screen’s internal frame. The glass-covered Relative Humidity (RH) sensor was made by the renowned precision instrument maker, Rotronic AG of Switzerland, which was founded in 1965. The firm made its first electronic temperature and humidity instrument in 1967. Meteorological records have been collected in Australia from the 1800s. The records were collated, published and used as a basis for weather forecasts. Many sectors, such as maritime and agriculture industries, have relied on these figures for making important decisions. The quality and placement of the meteorological instruments used to measure temperature and humidity are of utmost importance for accuracy. In early colonial times, there were no national standards for meteorological instruments that would allow for accurate figures and comparisons. Once the Bureau of Meteorology was established (around 1908 to 1910) the department installed Stevenson screens throughout Australia, many at lighthouses and light stations, and the measuring instruments were standardised. The Stevenson Screen was named after its inventor, Scottish Civil Engineer Thomas Stevenson (1818-1887) who was also the father of Robert Louis Stevenson, author. Stevenson developed the small thermometer screen around 1867. It had double-louvred walls around the sides and a top of two asbestos sheets with an air space between them and was thickly painted with a white coating that reflected the sun’s rays. This design was modified in 1884 by Edward Mawley of the Royal Meteorological Society. Standards were set for the locations of the screens and instruments, including their distance above ground level and the direction the door faced.Stevenson screens played a significant part in providing a standardised shelter for all meteorological instruments used by the Australian Bureau of Meteorology from about 1910 until 1994. The readings from the instruments gave the meteorological statistics on which weather forecasts throughout Australia were based. This Stevenson screen was used locally at Cape Otway, along the Great Ocean Road in southwest Victoria, so contributed towards our local forecasts and weather warnings.Stevenson screen, original, from the Australian Bureau of Meteorology’s weather station at the Cape Otway Lighthouse. The screen is a white wooden cupboard with a slanted cover raised above the top. The top has ten drilled ventilation holes, and the sides and door are made of downward-slanting double louvres. Two brass hinges join the door to the lower edge of the screen and a metal fitting at the top edge allows for a padlock closure. The screen is supported on four short legs, each with a hole drilled from side to side for fitting to a frame. Inside the screen are two wooden frames fitted with hooks and screws. The floor has three boards; one across the back and one across the front at the same level, and a board wider than the space between these boards is fitted higher, overlapping them slightly. Inside the screen, a pair of electronic instruments with short electric cables is mounted on a metal bracket with drilled holes in it. One of the instruments is a Relative Humidity (RH) probe. It is 26 cm long and is a glass tube with a filter on one end and an electrical connection on the other. It has inscriptions on its label, showing that was made by Rotronic AG, Switzerland. The other instrument is a Resistance Temperature Device (RTD) thermometer. It is 22.5 cm long and has a narrow metal probe joined to a hexagonal metal fitting. A brass plate on the front of the screen has impressed inscriptions. The screen is Serial Number 01/C0032, Catalogue Number 235862.Stamped into brass plate "CAT.

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 is a set of 1photographs of surveyors in the field measuring distances using chains, taking observations using theodolites and operating electric distance measurement equipment. They were probably employed in establishing mapping and geodetic control operations or the surveyors may have been in training. The photos were most likely taken in the 1950s and 1960s. Photos .1P to .6P feature personnel setting up geodetic survey chaining equipment to measure distances. The surveyor in Photo .5P is LTCOL Howard Angus Johnson MBE who served from 1936 to 1954. The RA Svy surveyor in photos .7P to .12P were using a theodolite to take angular measurements. They were usually supported by an observer who recording their readings on a booking form. The surveyor in Photo .10P and .11P is LTCOL Jorge Gruszka, who served from 1955 to 1985. He was CO of the Army Survey Regiment from 1982 to 1985. The surveyor in photo .13P is cutting an identification blaze on a tree using a hammer and chisel. The tellurometer in Photos .14P to .16P was a MRA1 microwave Electronic Distance Measuring instrument (EDM) introduced in 1958. It and later models were man-portable systems that improved geodetic survey efficiencies for rapid network extension and densification replacing triangulation with EDM and theodolite traverse sometimes using Bilby Towers to extend line lengths. The surveyor with the slouch hat is Colonel James ‘Jim’ Leslie Stedman, who served from 1941 to 1978. He was Director of Military Survey from 1975 to 1978 and was appointed as Colonel Commandant (honorary appointment, Retd) of the Royal Australian Survey Corps from 1978 to 1983.

This general purpose Multi-meter was manufactured after 1950 and used by the SEC Vic (Kiewa Hydro Electricity Scheme) from that date until late 1900's. It was used to measure very small voltages associated with the operation of the various Hydro Generators. The readings were able to be shown by the resistor in use in the current circuit. During this time period, high quality testing instruments were either sourced from Europe or England. This particular meter was manufactured in the Netherlands. This type of "old" analogue meter was replaced by digital meters whose electronic components are a fraction of the size of the older analogue ones.This analog General Purpose multi-meter is quite a large (for handheld mobile) apparatus which permits the easy monitoring of electrical variations within the large SEC Victoria Hydro Scheme's electrical generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro schemes was achieved from the mid 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce inclusion of skilled and unskilled migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years.This General Purpose Multimeter is an analogue meter i.e. it has a needle arm that moves across a scale of divisions. This is a large(hand held) device due to the mechanical movement system within and the large size of its electronic components of its circuitry.There are two black bake-lite push buttons operating the wire inserts Positive/negative leads at the top. The meter (protected with a glass window) has clearly marked graduations (top - volts, bottom amperes). Below this are two bake-lite dials (left "potentiometer the right one measuring range selector). Below this is a "dial" switch to input the desired resistance measuring range "V" Front "H&B ELIMA" and to the right Elavi 15n. 0n the front side is a label "STATE ELECTRICITY COMMISSION OF VICTORIA TRANSMISSION DEPT E.C.No." On the bottom of the base is a stenciled layout of the battery "layout" including the fuse .

This Favag Timer apparatus was a part of the first electronic control system -(1960's), in Victoria), which worked using telephone stepping selectors to convey a change in voltage providing a regulated pulse from the control centre(Mount Beauty) to the remote Power Stations opening and closing (stop/start) of various devices at the Power Station and a return signal confirmed the action taken. Testing of this unit was carried out using a "dummy" device at the remote Power Station so as not to disrupt the power plant's operation. This timer was one of many electrical apparatus connected to the large SEC Victoria Hydro Scheme's electrical power producing generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro Schemes was achieved from the early 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce,inclusion of skilled and unskilled, migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years.This Favag Timer was one of the crucial pieces of equipment that made it possible for the Mount Beauty Terminal Station to control the operations of these Power Stations; McKay, Clover, West Kiewa Power Stations and the Dederang Terminal Station.This aluminium and anodised "FAVAG" (pulse) timer is fastened to a base structure which comes with its own metal cover that is fastened by two metal hooks. From the top of these hooks runs a thick leather "carry" strap.The instrument, itself, a small "micro motor" at one end tape feeding spool on the other. Aluminium metal structures offer a preventative barrier against any electronic spikes from static electricity sources. There are two toggle switches to the bottom right hand side and twelve coloured "pin" connection points.There is a sliding access sleeve which exposes a circuit board.with various leads fastened on each side. In front of one of this slide are two "screw in" fuses, spare fuses are in a small envelope taped above. Circuit diagrams are etched white on black background on the top face of the main structure. At the base of the back section is a two pronged input terminal.
