First available in ScubaPro’s catalogue in 1966, the ScubaPro Automatic Decompression Meter was a break through in diving technology and a forerunner to the modern dive computer. The meter attempted to calculate nitrogen absorption based on dive time and depth. This was done mechanically instead of electronically, and without the benefit of any actual computing. The Automatic Decompression Meter was introduced just a year after ScubaPro’s most successful product – the ScubaPro Jet Fins – which still remain popular today.

Bushfire behaviour is influenced by many things including temperature, relative humidity, forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), and also bushfire size, shape and direction. Fuel arrangement is as important as fuel quantity (tonnes/ha). Fibrous and ribbon bark, together with elevated and near-surface scrub fuels act as ladders which lead flames into the tree canopy. But the availability of fuel to burn depends largely on its moisture content. When it exceeds 20-25% not much will burn, whereas 12-15% is generally ideal for fuel reduction burning, but if the moisture content drops as low as 7-10% virtually everything will ignite, and fire behaviour becomes extreme. During the afternoon of the Ash Wednesday bushfires on 16 February 1983 fuel moisture contents were recorded at Stawell as low as 2.7%. Fine fuels like leaves and bark can rapidly absorb moisture after a shower of rain, or from the air when the Relative Humidity (RH) is high, and the temperature is low. Conversely, they can also dry out very quickly. So even though the overall fuel quantity in the forest doesn’t change, the fine fuel availability can increase rapidly from zero after rain to many tonnes per hectare as the fuel dries out. This can happen over a few hours on hot and windy days. Heavy fuels like logs on the ground take longer to dry out. Since the 1930s foresters, firefighters and researchers have been working to develop quick and reliable techniques for measuring fuel moisture content. One of the most accurate methods is slowly drying a sample of fuel in a conventional oven for 24-48 hours to remove all the moisture and measuring the weight difference, but this takes time and is not practical in the field when rapid measurements are needed. But oven drying is often used as a benchmark to compare other methods. Microwave ovens are faster but can cause uneven drying and even char the fuel. They are also not very practical for use in the field. Some mathematical models rely on weather records such as rainfall, wind speed, evaporation, cloud cover, shading, relative humidity, slope, aspect and season of the year to predict soil and fuel moisture. The Keetch-Byram Drought Index of soil dryness is the most common. But complex fuels with leaves, twigs, grass etc make the predictive models often inadequate for fine fuels. The most common technique in Victorian forests until recently was the trusty Speedy Moisture Meter. Originally developed in England during the 1920s for measuring moisture in wheat and other grains it was adapted for Australian forest fuels in the 1950s (I think). Fuel was first ground using a Spong mincer, often attached to the bullbar of a vehicle, and a small sample placed into the Speedy together with a measure of calcium carbide and then sealed. A chemical reaction created gas pressure which was read on the external dial. There were important techniques with cleaning, mincing and using the chemicals with the Speedy to give reliable readings, but it was quick, inexpensive, robust, portable and practical in the field. It was used routinely before igniting a fuel reduction burn or measuring fuel moisture differentials on slash burns. But in about 1996, Karen Chatto and Kevin Tolhurst from the Department’s Creswick Research Station developed the Wiltronics Fuel Moisture meter which measured electrical resistance. Wiltronics is an Australian owned company operating from Ballarat. The final result was a kit that was portable, accurate and could reliably measure fuel moisture contents between 3% and 200%. Although expensive, it is now widely used by fire agencies around the world which has virtually relegated the Speedy to the back cupboard.Prototype Fuel moisture meterT-H Fine Fuel Meterforests commission victoria (fcv), bushfire, forest measurement

The Forest Fire Danger Index (FFDI) was originally invented by the grandfather of Australian bushfire science, Alan Grant McArthur, during the 1950s and ‘60s. Alan published his landmark paper, “Controlled burning in eucalypt forests” in 1962. Leaflet No. 80, as it was known, proved a turning point for forest and fire managers across Australia. More importantly, Alan was very practical forester and wanted his work to be useful to people in the field, so after several iterations he came up with the now familiar circular slide rule called the Forest Fire Danger Meter (FFDM).  The Mk 4 version first appeared in operational use in 1967. Two Forests Commission staff, Athol Hodgson and Rus Ritchie, built on McArthur’s pioneering work and by applying their own practical experience, developed a modified version in the late 1960s called the Control Burning Meter which was better suited to Victorian forest conditions.Introduced to the FCV in 1970Control burning meterbushfire, forests commission victoria (fcv)

Edward ( Ted) Salamy (1903-1977) succeeded his father in business in Warrnambool as a jeweller and was at 179 Liebig Street when he retired in the 1960s. On 1st December in 1924 he obtained an amateur radio licence ( Call sign A3AJ). This was the 35th licence issued in the State of Victoria and the first in Warrnambool. The original licence cost two shillings and sixpence. Amateur radio, still a popular hobby today, was particularly important in the 1920s when few people had radios of any sort and there were no provincial radio stations. People were able to access amateur radio sets to listen to such broadcast as overseas cricket matches. This amateur radio set is of considerable historical importance as it belonged to Ted Salamy, credited with being the first to operate an amateur radio station in Warrnambool.This is a rectangular box containing five valves, a radio frequency mechanism and three coils with fine copper winding. The mechanisms are connected by wires and metal screws. The box has a raised black -composite material front which has a voltage meter, three switches or knobs and a tuning dial.

The most common technique to measure fuel moisture content in Victorian forests until recently was the Speedy Moisture Meter - which is essentially a pressure cylinder. Originally developed in England during the 1920s for measuring moisture in wheat and other grains it was adapted for Australian forest fuels in the 1950s. Fuel was first ground using a Spong domestic food mincer, often attached to the bullbar of a vehicle, and a small measured (using the beam balance) sample placed into the Speedy together with a measured amount of calcium carbide and then sealed. The chemical reaction between the moisture in the fuel and the calcium carbide created acetylene gas; the pressure of which was read on the external dial which gave the read-out as the moisture content (percentage of net weight) of the sample. There were important techniques with preparing the minced samples, using the chemical and the subsequent cleaning of the Speedy to give reliable readings, but it was quick, inexpensive, robust, portable and practical in the field - it gave readings which were reproducible to within +/- 0.5% moisture content. It was used routinely before igniting a fuel reduction burn or measuring fuel moisture differentials on slash burns. In about 1996, Karen Chatto and Kevin Tolhurst from the Department’s Creswick Research Station developed the Wiltronics Fuel Moisture meter which measured electrical resistance.First reliable tool for measuring bushfire fuel moisture content in the fieldSpeedy Moisture Meter in wooden boxmanufacture's marks and instructions on usebushfire, forests commission victoria (fcv)

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).

When this AVOMETER was being utilised in the early 1950's it was at the "leading" edge of electrical measuring instrumentation.The first meter was produced by Automatic Coil Winder and Electrical Equipment Co. in 1923. This model was produced in the time from 1933 to 1951 when it was superseded by the most popular model, Model 8 (1951 to 2008).This AVO meter brought the measuring of three electrical power indicators i.e., amps, volts and ohms into one measuring unit. By using a "one fits all" unit, the carrying of separate measuring devices was reduced considerably. The need for a mountainous and a large area of operational requirements, such as the SEC Vic Kiewa Hydro Electricity Scheme, to minimise the weight of equipment carried by electricians and technicians was of the utmost relevance. The significance of this meter to the Kiewa Valley region relates to the impact of modern technology (at that time) upon a mainly rural environment. This equipment shows how the boost of "modern" equipment into the area because of the "Hydro Scheme" was facilitated a lot faster than would have taken under "normal" evolutionary time. The speed of information on all "new technology" had a relatively slow assimilation rate to those living in rural communities. This AVOMETER is a Model 7 MKII, production pre 1951. This meter measures electrical Amps, Volts and Ohms and has two internal batteries for its power. The main casing is made from aluminium with a bake-lite front. The front has a "window" detailing, with a needle pointer, the amount of electrical power being tested. There are two big dial switches, detailing Direct Current(DC) and Alternating Current(AC) when reading measurements of Ampere, Voltage and Ohms for power. This meter took the place of three or four meters used earlier. Modern meters (2000 onwards) have become digilised and are considerably lighter in weight and smaller. There are two electrical connection leads (one black and one red) each has a removable clasp and is 125cm long.Molded on the front centre panel " UNIVERSAL AVOMETER".
