The cylindrical cardboard container with lid formerly contained a ventometer, a small simple tool for measuring wind speed. It consisted of a clear tube containing a small diaphragm which had a hole in the bottom for wind to enter. Once the wind entered the tube it pushed up the diaphragm, indicating the rate of velocity. Ventometers were common devices that have since been replaced by more sophisticated measuring equipment, such as digital air speed meters. Further information on this particular example, including perhaps the name of the manufacturer, may survive on the container but this has not been recorded. The small simple tool for measuring wind speed pre-dates the electronic devices at Gabo Island.Tubed shaped cardboard container with lid to house instrument for measuring.

From Scarborough Maritime Heritage Centre: A Yacht Log was a nautical instrument for measuring a vessel's speed and distance travelled. When navigating a ship it is essential to be able to estimate the boat's speed and distance travelled to determine its position at sea. In times past the only way to measure a ship's speed was to throw a wood log into the water and observe how fast it moved away from the ship. In the 16th century, the log was fastened to a rope knotted at set intervals. The log was thrown over the stern (back) of the vessel and a crew member counted the number of knots that were paid out in a set time. From this they could estimate the speed of the vessel through the water. This was known as streaming the log and is also the derivation of the knot as a measurement of nautical speed. In 1878, Thomas Ferdinand Walker (1837–1921), an engineer in Birmingham, patented a mechanical log in which a recording instrument was attached to a rail at the stern of a vessel connected by a long cord with a rotor which was towed behind the ship. The instrument dial recorded the distance travelled. The 'Log' at the Heritage Centre was recovered from a skip in Scarborough and was one of the first artefacts collected by the volunteer group. It is made of brass with a ceramic dial, with the main scale marked from 0 to 100 nautical miles and an inset dial marked from 0 to 10 miles. It has a fixing plate, on which it can turn, with which it would have been attached to the 'taffrail', the rail at the stern of a ship, usually on the starboard side. The Walker’s Excelsior Mark IV instrument was designed for smaller vessels, such as yachts, launches and fishing vessels. Its exact date of manufacture cannot be determined but this design was manufactured in the first half of the 20th century. These mechanical logs have now been superseded by electronic equipment such as GPS navigation instruments.This instrument was made by a significant nautical instrument manufacturer and demonstrates the innovation needed at the time for improved navigation and safety at sea.Timber Box containing an instrument for measuring speed and distance. There is a brass, cased log with a white enamel dial. It also includes a towing cord and cylindrical rotator. The box has paper labelling on the front and also the inside of the lid. The label on the inside of the lid has instructions for use. Although the lid is hinged it has broken off and is separate. The hinges remain attached.Enamel Dial: Walkers Patent Excelsior Yacht Logmaritime, maritime history, tool, navigational tool, navigational instrument, navigation, sailing, walkers, maritime technology, walker & son

In the 1600s, William Harvey realised a finite amount of blood circulates in one direction through the body. Jean Léonard Marie Poiseuille introduced the mercury hydrodynometer in the early 1800s for measuring blood pressure. Karl von-Vierordt created the sphygmograph in 1855 and, in 1881, Samuel von Basch created the sphygmomanometer, distinct improvements on the hydrodynometer. In 1896, Scipione Riva-Rocci developed the mercury sphygmomanometer. American neurosurgeon, Harvey Cushing, was an early adopter, and advocate for monitoring patients during surgery and anaesthesia. Blood pressure monitoring is still an essential component of evaluating a patient’s condition.This blood pressure kit is housed in a rectangular, vinyl covered box with metal handle and press-stud lid release mechanism. The lid opens upwards and the glass blood pressure valve and plastic scale is attached to the underside of the lid. The measurements are written in black and go up in increments of ten, from 0 to 300. The glass valve has unidentified increments labelled in red, which is housed within a metal cylinder. The bellows is attached to the measuring valve via a dark green pressure cuff and rubber hose.Blue sticker affixed inside the kit: JOHN MARUM Ornate manufacturer's label: THE ARMOURED / ELLISCO / SPHYGMOMANOMETER / MADE BY / ELLIOTTS & AUSTRALIA DRUG / [indecipherable] LTD / CENTEN[indecipherable] MODELharvey cushing, blood pressure, measurement, anaesthetics, john marum, sphygmomanometer, elliotts & australian drug pty ltd, centenary model, cuff, bellows, ellisco, armoured

This is an early example of the Boyle's Anaesthetic Machine which was to become widely used throughout the world. The plaque on the wooden plinth suggests it was a display model from the medical equipment distributor Charles A King of London.The gas anaesthesia apparatus is mounted to a rectangular wooden base. It comprises two long, vertical glass cylinders held in place with metal brackets which are connected to a glass chloroform vaporiser container via metal tubes and associated valves and connections. The bottom of the glass flasks have outlet connections and inscriptions on the glass to measure volume. The chloroform vaporiser and adjacent glass ether vaporiser also have volume measurements etched on the glass, and the latter is the same height as the former but is larger in diameter. Both are connected via metal tubes and include outlet pipes that have associated cork stoppers. The maker's details are provided on a brass plaque attached to thewooden platform.A. Charles King Ltd.

Bushfire behaviour is influenced by many factors including temperature, relative humidity (RH), forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), as well as fire size, shape and direction. Temperature and relative humidity have major impacts on fuel dryness and therefore upon the availability of fuel for combustion. A thermo-hygrograph measures and records both temperature and humidity. It produces a continuous record by drawing ink traces on a paper chart held in revolving cylinder. Humidity is measured by shortening or lengthening of a bundle of specially treated human hair. Temperature is measured by means of a laminated bi-metal strip of temperature-sensitive metals which bend differentially with temperature change. The recording drum is driven by clockwork which may be geared for rotation intervals of daily, weekly or monthly periods. This particular instrument is a seven-day recorder. Serial number 10186 which probably dates from about 1960.

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)
