PRODUCT SHOWCASE Hioki thermometers for food applications The new Hioki 3441/2 series of intelligent thermometers from Nilsen Technologies have a variety of probes including K-type sheaths and surface-type probes, making them highly suitable for use in food production and preparation. For wet environments, the Hioki 3442 also has a one-piece moulded resin construction. The thermometers will read from -100°C to 1300°C, making them suitable for use over a very wide range of applications, from liquefied gases to ovens and kilns. Resolution from -100°C to +200°C is 0.1°C. They can store maximum and minimum temperatures in the measurement time interval, and both maximum and minimums can be read at any time by pressing one button. The display can also be held for later review, especially handy in poor light conditions. For more information, contact Nielsen Technologies, 150 Oxford St, Collingwood Vic 3066.

Eurovox to make satellite vehicle guidance systems in Magellan deal Eurovox, Australia’s largest supplier of automotive audio entertainment systems to vehicle manufacturers, has recently signed an agreement with US-based Magellan Corporation to design, develop and manufacture satellite-aided in-vehicle navigation systems for the Australian and New Zealand markets. As well as using the licenced Magellan vehicle navigation technology, Eurovox will also develop navigation equipment for original equipment manufacturers and importers plus commercial and consumer applications. Eurovox will incorporate Mag-ellan’s latest turn-by-turn vehicle navigation and information technology which incorporates satellite positioning, patented inertial navigation capability and digital map-matching. This provides both visual and voice-prompted instructions for the driver. Managing Director of Eurovox, Paul Miller, said that the deal with Mag-ellan would mean that his company would now be able to provide the Australian automotive market with the very latest in mobile information systems. Eurovox boasts the most technically advanced production, engineering and R&D facility of its kind in Australia, with its own sheet metal and harness-making divisions. Offering manufacturers and importers a total car audio design, development and manufacturing facility, Eurovox-built products are found in a large percentage of vehicles manufactured or sold in Australia.

The speakers are nothing if not imposing. At 2.2m tall and weighing some 45kg, they are claimed to produce a well sustained bass response with the clarity and presence that only a true electrostatic speaker can provide. Frequency response is 40Hz-20kHz with a sensitivity of 84dB/W. Impedance is 4Ω. Each unit is based on two identical electrostatic panels with mechanically-separated bass and treble sections. The ultra-thin diaphragm has a moving mass equivalent to a sheet of air less than 3mm thick. The hand-built enclosures are craft- ed from 32mm natural timber and each occupies a floor area of 0.4 square metres. A wide selection of custom timber finishes is available. To complement the electrostatic speaker range, Vass has released a "pyramidal" subwoofer (also shown in the photograph at right). It is available in a passive version (for use with electrostatics) and a powered 200W active version (for use with conventional speakers). Constructed from 32mm MDF, the 50 x 50 x 50cm subwoofer features two 10-inch bass drivers in a 50 litre infinite baffle enclosure. -3dB point is at 30Hz, with -10dB at 20Hz. Vass speakers are available through selected distributors Australia-wide. For more information, contact Vass Electronics Pty Ltd, Unit 1, 42-44 Garden Bvde, Dingley, Vic 3172.

There are 4000 moves built into the memory and 40 famous ‘grand master’ chess games pre-programmed in. It runs on four ‘AA’ batteries and is priced at $99 (not including batteries) from all Dick Smith Electronics stores, by mail order or from the Dick Smith Powerhouse stores.
