Tester Direct Current, mid 1900's
This tester was used between 1950 and 1980's. As part of the Occupation, Health and Safety requirements, equipment used to monitor the performance of electricity producing generators, regularly, hand held testers were used to check the insulation and the "earth" pin were up the the required operational levels. As the generators and their ancillary monitoring equipment was spread over a large area and cumbersome to service small hand held devices were required. These had to always be safe for the user to operate. A selected range of high quality meters were recalibrated every two years in the Meter and Calibration Laboratory at Yarraville(near Melbourne) This meter is very significant to The Kiewa Hydro Electricity Scheme because it was an integral part of maintaining the electricity producing water driven generators of the power stations. The reason why this meter was so essential is that provided the safety check on equipment used to monitor each Hydro Generator that they were complying within the grid network parameters. Grid parameters are set so that if there is an electrical fault on the system, that fault can be attended to with a very small change in the output stability of each generator. It is essential that the voltage of the network remain within the set limits. Generators are at Dartmouth, Mackay, Clover, West Kiewa, Yarrawonga, Cain Curran and three Power Stations in the Thornton area.This hand driven current generator produces 500 volts by winding the handle(on funnel curved side) to keep the voltage constant(one minute per test). The whole body is made from caste aluminium. One of the functions of this meter is to test the isolation resistance of any equipment being tested. This is to see if that equipment is safe to handle(no electrical shocks). The second function is to test the earth pin of any portable electrical equipment. The turn key on one side can direct which function is required(marked insulation or continuity). On the top side(enclosed in a glass fronted marked scale) is a continuity scale(top) and an insulation scale(bottom). This is covered , when not in use by "flip up" lid with manufacturer's details and name of the instrument. Opposite the winder are two screw tight knobs. One marked earth(left side) and one marked line(right side). On the top and next to the glass windowed scales in a post manufacture SEC Vic equipment equipment ID number.

Equipment - Vaporiser, c. 1958
The Fluotec vaporizer was made to administer only halothane (Fluothane). It was one of the first vaporizers made for use with only one anesthetic, and one of the first to use a bimetallic coil for temperature compensation.The bimetallic coil is part of the valve that controls how much of the carrier gas enters the vapor chamber to vaporize the anesthetic.Modern vaporisers still use this bimetallic coil technology today. Serial No: 5040 Patent No: 814427 A ready reference “calibration card” came attached to these vaporizers. The card was printed with a scale that indicated the concentration of halothane produced at different flow rates and dial settings.This item does not have a reference card with it.This Flotec vaporiser holds historic significance as a very good example of an early model piece of equipment for halothane only administration. Modern vaporisers still use the bimetallic coil technology and therefore this object has scientific and research significance.Small metal stand with 3 rubber feet, Main metal cylinder body housing the bimetallic coil.

Instrument - Survey Chain, Chesterman, Gunter's Survey Chain
Before metric measurement was introduced land was measured in chains and links. The chain was a precision part of a surveyor's equipment. It required frequent calibration, yet needed to be sturdy enough to be dragged through rough terrain for years. A standard survey chain is 66 feet (or 20.117m) long and made up of 100 links. Each link is 7.92 inches (approximately 201mm) long, measured from the inside of the loop. The handles are for tensioning the chain in use, they are not part of the length of the chain. In pre-metric units, there were 80 chains to 1 mile (equals 1.609km) This surveyor’s chain has an 8-inch link pitch, with markers at 10 link intervals. This metal surveyor’s chain (or Gunter's Chain) has an 8-inch link pitch, with markers at 10 link intervals, and handles at either end. A Surveyor’s Chain was 66 feet long, and made up of 100 links connected by two rings. A link in measurement includes the two rings at each end. gunter's chain, survey chain, surveyor s chain, perch, rood, surveying -

Instrument - Scale, George Salter & Co, ca. 1886
There were at least three 1880s vessels named Lady Loch, all built in Victoria; a river launch (ca 1884-ca 1916, originally named Lady of the Lake), a steamer ferry (1884-1920s) and a government lighthouse tender steamer HMV Lady Loch (1886-1962.) The spring balance scale was part of the equipment on the HMV Lady Loch. The scale was made by the renowned company Salter Weighing Machines in the United Kingdom. It was made to Silvester's patent design. Salter Weighing Machines, Britain, began making spring scales in the 1820s. In 1908 Salter opened up an Australian branch named Salter Scales Pty. Ltd. The scale, marked HMV SS Lady Loch, would be suspended by its top ring, a basket or other container is hung from the hook, and the items inside the basket then pull downwards on the hook, which stretches the springs inside the works. The pulling action moves a rack and gears a calculated distance and the gears turn the pointer on the dial to indicate the weight of the goods. This scale measures up to 200 pounds capacity. The HMV SS Lady Loch was an iron steamship built in Footscray, Melbourne, by Campbell, Sloss and McCain in 1886 for the colonial Victorian government’s Department of Trade and Customs. It was armed with a 6-inch gun and two 1-inch Nordenfelt guns. The Sydney Morning Herald of 27th January 1888 describes the vessel in detail. It even comments on the interior of the Saloon “The wood work … is on a very elaborate scale and is exceedingly neat …”. The HMV Lady Loch performed Customs duties, and serviced the lighthouses along the coast. The scale could have measured goods for the Customs Tax, or for measuring out supplies for the lighthouse keepers. The vessel was named after Lady Elizabeth Loch, wife of Sir Henry Loch, Governor of Victoria from 1884 to 1889. In 1932 Lady Loch was converted to a hulk and used in Brisbane, and finally scuttled in 1962 at Moreton Bay, Queensland.The scale has importance due to its connection to the 1886 HMV Lady Loch, a vessel of great significance to Melbourne’s shipbuilding industry. It was the largest auxiliary vessel in the Victorian Colonial Government’s fleet and the first prominent vessel launched by Melbourne’s shipbuilding industry. The scale is also important for its connection with the colonial navy's Custom's work, as the scale was available to weigh goods that could attract taxes and deal out goods for distribution to lighthouse keepers. The HMV Lady Loch was also important part of Victoria's maritime history for its communication and support of the lighthouse keeper's along the coast of Victoria.Scale; Salter's spring balance mechanical hanging scale, brass and iron. Equally spaced marks around the circular dial have values from 0 to 200 in increments of 10, each increment is also divided into 10. An iron ring is attached to a fitted loop on the top of the scale, and an iron hook is attached to the fitted loop onthe bottom of the scale. A moving pointer attached to the centre of the dial has a calibration screw joined to its base. Four screws fix the brass face to the works at the back. There are stamped and embossed inscriptions. Made by Salter in Britain, to Silvester's Patent design. The scale was once equipment carried abourd the steamship HMV SS Lady Loch.

Gunter's Chain
Before metrication was introduced into Australia in the 1970s land was measured in chains and links. Many old parish plans show length measurements in chains and links. Area was shown in acres, roods and perches. Gunter's chain was used for measuring distance in surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). Gunter developed the measuring chain of 100 links. The chain and the link, became statutory measures in England and subsequently the British Empire. After metrication units of length were measured in meters and area in hectares. The chain was later superseded by steel ribbon tape.The 66 foot long brass Gunter's Chain is divided into 100 links (each 7.92 inches long), and marked off into groups of 10 by shaped tags which simplify intermediate measurement. It was heavy but flexible enough to be dragged through the bush on surveying transects.(Hence the common forestry term "chainman). The chain was a precision part of a surveyor's equipment. It required frequent calibration, yet needed to be sturdy enough to be dragged through rough terrain for years. It has brass hand grips at each end of chain. 1 chain = 100 links = 22 yards = 66 feet = 792 inches. 10 chains = furlong 80 chains = 1 mile 1 acre = 10 square chains = 4 roods (1/4 acre) = 40 perches.forest measurement, surveying, forests commission victoria (fcv) -

Instrument - Ship Compass Sections, 1886
A ship's compass played an extremely important role in navigating the ship from the port to its destination. If there was a slight inaccuracy in its calibration the ship could miss its destination and crash or be wrecked. The Falls of Halladale was an iron-hulled, four-masted barque, used as a bulk carrier of general cargo. She left New York in August 1908 bound for Melbourne and Sydney. In her hold was general cargo consisting of roofing tiles, barb wire, stoves, oil, and benzene as well as many other manufactured items. After three months at sea and close to her destination, a navigational error caused the Falls of Halladale to be wrecked on a reef off the Peterborough headland on the 15th of November, 1908. The captain and 29 crew members survived, but her cargo was largely lost, despite two salvage attempts in 1908-09 and 1910. The Court of Marine Inquiry in Melbourne ruled that the foundering of the ship was entirely due to Captain David Wood Thomson's navigational error, not too technical failure of the Clyde-built ship. The Falls of Halladale was built in1886 by Russell & Co., at Greenock shipyards on the River Clyde, Scotland for Wright, Breakenridge & Co of Glasgow. She was one of several designs of Falls Line of ships named after waterfalls in Scotland. The company had been founded between 1870- 1873 as a partnership between Joseph Russell, Anderson Rodger, and William Todd Lithgow. During the period 1882-92 Russell & Co. standardised designs, which sped up their building process so much that they were able to build 271 ships during that time. The Falls of Halladale had a sturdy construction built to carry maximum cargo and able to maintain full sail in heavy gales, one of the last of the 'windjammers' that sailed the Trade Route. She and her sister ship, the Falls of Garry, were the first ships in the world to include fore and aft lifting bridges. Previous to this, heavily loaded vessels could have heavy seas break along the full length of the deck, causing serious injury or even death to those on deck. The new, raised catwalk-type decking allowed the crew to move above the deck in stormy conditions. The Falls of Halladale shipwreck is listed on the Victorian Heritage (No. S255). She was one of the last ships to sail the Trade Routes from Europe and the Americas. Also of significance is that the vessel was one of the first ships to have fore and aft lifting bridges as a significant safety feature still in use on modern vessels today. The subject model is an example of an International Cargo Ship used during the 19th and early 20th centuries to transport goods worldwide and represents aspects of Victoria’s shipping industry. The compass sections are also significant for belonging to the compass of the Falls of Halladale. It was a critical part of the ship's equipment. Compass sections, two; brass disc with a round object on a pedestal, together with a glass disc with a metal frame and insert in the centre. Both items were recovered from compass on the wreck of Falls of Halladale.

Barometer Anoroid, circa mid to late 1900's
This barometer was part the hydrology and forestry groups working within the SEC Vic Hydro Scheme from the initial appraisal review long before any construction began in the 1940's. The river flows and rainfall patterns had to be established before any construction of holding dams or tunneling could commence. This barometer is very relevant to the Kiewa Valley history because it presents the high degree of professional and technical information required at the time before implementing the "Scheme" upon the virgin alpine region and its effects upon the "natural" flows of the rivers within the Kiewa Valley. Time since the start of the project has verified the use of instruments such as this barometer and the information gained from its use that the success of any large impact upon a sensitive environment requires a thorough and systematic study before implementation. Weather records were kept of temperature, wet-bulb temperature, wind direction, speed and barometric pressures. To record barometric pressure a meter was devised with a clockwork mechanism which took one week to do a revolution. A chart was fitted to a drum and had an ink pen shaped like a little shovel. The shovel was filled with ink and was checked daily. To calibrate the barometer it was sent to the Melbourne General Post Office to be compared against the one there (at sea level). After calibration it was sent back to the Bogong Camp.On plaque on top side."NEGRETTI & ZAMBRA" underneath this and in smaller print "TRADE MARK" below this "LONDON" On the bottom and in small print "HOBART DUFFPty Ltd COLLINS HOUSE MELBOURNE C1"kiewa hydro electricity scheme, victorian state electricity commission, transformers, resistors, barometers -
